The Trials and Tribulations of Making Raspberry Jam

Thursday, June 10th, 2010

jars of raspberry jam

I used to think that making jam was a quick and painless task. Although peeling and/or cutting up apples or strawberries can take some time, the jam-making process is generally pretty easy: just boil your fruit with some sugar and maybe a packet of pectin and then can. And, if you're feeling especially lazy, you can avoid sterilizing jars and boiling by simply plunking your cooled preserves into baggies to freeze, which is what I do with my tomatoes.

Well, all thoughts about quick and easy preserving changed for me this week. Making meyer lemon marmalade, apricot and blackberry jam, and apple butter may be fairly simple projects, but, as I found out, cooking up a batch of raspberry jam can be time consuming and a bit maddening.

My adventure began with a bumper crop of sweet red raspberries in my backyard. The little thornless raspberry plant I purchased four years ago has turned into 15 feet of lush vines laden with berries. There were too many to just eat out of hand (although trust me, we did try). So, with literally a bucket or more of ripe raspberries about to go bad, I decided to try my hand at making raspberry jam. Little did I know my jam adventure would take two days, two recipes, and two trips to the store.

Problems

Here were the problems I encountered:

Seeds: The first issue to contend with when cooking with raspberries are the tons of little seeds embedded in the berry's flesh. Although I barely notice them when eating the fruit fresh, they take on the consistency of small pellets that settle between the teeth when preserved. Plus there are literally thousands of them in a bucket of berries.

Watery consistency: My other main problem with making raspberry jam is that this fruit has very little substance, so once you cook it down there is hardly any fleshy pulp to turn into jam. Even after I added some pectin, I ended up with something closer to a thick syrup than a jelly or jam.

Sweetness: My third and final problem with making raspberry jam was the level of sweetness those perfectly-ripe berries imparted. Although I love eating just-picked sweet berries off the vine, they were so sweet that my jam ended up tasting too sweet once I added the sugar.

I ended up overcoming all these problems, and learned a lot along the way. I wish someone had told me how to deal with the mess of seeds, lack of substance, and overtly sweet taste of ripe raspberries in jam before I started, but when I tried to look up these problems in my cookbooks and online, there were very few resources that raised these topics. So, if you're interested in making raspberry jam yourself, read on to learn from my mistakes.

Solutions:

setting the pulp and seeds in cheesecloth

Seeds: To remove the seeds from your jam, press your strained raspberry mixture through some layers of cheese cloth. You will still end up having some seeds in the preserves, but the majority will be removed. To do this, just place layers of cheese cloth in a large bowl and then pour your strained raspberry and sugar mixture into it. Do this before adding your pectin or any other fruit you may add to your jam. Roll your cheese cloth around the raspberry mixture and then press so the raspberry juice and pulp extract through the cloth but most of the seeds stay inside. Massage and press the cheese cloth until most of the pulp and juice is removed. Be sure to wait until the mixture has cooled enough to handle.

Watery consistency: My jam was so watery that a full pack of pectin plus a half of a pear (which is full of natural pectin) wasn't enough to make a firm jam. I therefore reboiled my preserves the next day with two more whole pears (which I peeled, seeded and grated). This gave my jam a fuller texture so it lays on my toast instead of running off it.

Sweetness: My big mistake here was simply adding too much sugar. Although most recipes added an equal amount of sugar to the berries (and some added 1 1/2 times more sugar to the berries), my berries were so sweet and ripe that they needed far less. Next time I will add a 1/2 cup of sugar to a full cup of berries and then taste the jam to determine if I need more. Fixing my overly sweet jam this time, however, ended up being fairly easy. I just added more pears to the mix in the second round of boiling (on day two). The pears natural pectin really helped thicken the consistency and as the jam was already sweet, I refrained from adding more sugar so the tart and sweet flavors ended up balancing out nicely. This brought me closer to the 1/2 cup sugar/1 cup fruit ratio I should have used to begin with.

So now that I've gone through the jam-making trenches, I hope my advice is helpful for anyone out there wanting to make their own jars of homemade raspberry jam. And, although removing the seeds in cheese cloth can make preparing raspberry jam more time intensive than making other preserves, the flavor of ripe raspberries all year is worth it.

Raspberry and Pear Jam

Makes: 6 jars of jam

Ingredients:

4 cups ripe raspberries
2 1/2 pears (peeled, seeded, and grated)
2 cups sugar (plus more if needed)
1 box fruit pectin
1 Tbsp fresh lemon juice
1/4 cup water
Cheese cloth

Preparation:

1. Place your berries, sugar, lemon juice and water in a pot. Heat fruit on medium high heat until it starts to break down. When mixture has a liquid consistency, lower heat and simmer for five minutes.

2. Pour raspberry mixture through a fine mesh strainer and into a bowl. Once the juices have poured through the strainer, pour the juice back into your pot.

3. Place cheese cloth (around 4 - 5 layers) in the now empty large bowl and set the raspberry pulp and seed from the strainer into it. Wrap cheese cloth around the pulp and seeds until you have a ball. Squeeze out any remaining raspberry juice and then massage the cloth ball to squeeze out as much pulp as possible while trying to keep as many seeds inside as you can. When you have squeezed out all the pulp you can, gently scrape the outside of the cloth to capture the remaining pulp and then discard the cheese cloth. Pour the raspberry juice and pulp into the pot.

4. Add your grated pears to the pot of raspberry juice and pulp and then bring the mixture to a boil for around one minute, stirring constantly so as not to burn the jam on the bottom of the pot.

5. Taste the jam. Add more sugar if needed and then lower heat to simmer.

6. Pour in the pectin and simmer for another five minutes while stirring.

skimming out foam and seeds

7. Skim out the foam that will form at the top of the jam with slotted spoon or small strainer, picking up some seeds as well if you can.

8. Pour into hot sterilized jar to seal or let jam cool and then place into plastic containers or baggies to place in the refrigerator (to use within two weeks) or freeze.

Strawberry Jam

Sunday, June 7th, 2009

Chickens pecking around the backyard, kombucha fermenting on the shelf, beer brewing in the closet: there's been a lot of interest in DIY urban homesteading lately. For months now, I've been meaning to get into the slow-process stuff, like curing my own olives and making my own vinegar.

Then again, my homestead is a wee share house in Bernal, already stuffed with other people's tchotchkes. I've commandeered the tiny back patio with my buckets of tomato and potato plants; adding an olive crock and a vinegar barrel might be pushing it.

And honestly, I'm still wedded to the easy delights of jam. Like pie, it's a little bit of a production, but just like pie, no matter what you do, fruit+sugar=sweet fruity goodness. And like homemade pie, homemade jam is better than anything you can buy. Why? Because anywhere this side of Smuckers, you're using more fruit and less sugar when you make your jam at home.

Ah yes, the sugar issue. First off: most cookbooks call for way too much sugar. Why? The more sugar you put in, the easier it is to get a firm and reliable set. Sugar is also a preservative, and jam with a lot of sugar will last longer in your fridge. But capturing the essence of beautiful fruit is the whole point of jam, rounded out with just enough sweetness to bring a smile to your toast. Halve the amount of sugar in most recipes, and you'll do just fine.

For the same reason, I never use commercial pectins, like Sure-Jel. There's nothing wrong with pectin itself; it's a natural compound found in varying levels in all fruits. However, commercial pectin requires a lot of sugar to jump-start that jelling reaction, and the precise formulas turn canning into chemistry, with no adjustments for personal taste.

But with less sugar and no added pectin, won't your jam be a runny mess? Nope! There's an easy, just about foolproof way to get good jam every time, and all you need is sugar, lemon juice, and time.

strawberriesTake a look at this bowl.

That's 4 pints of strawberries, sliced, mixed with sugar and left to sit overnight until they've shrunken into little berry quarters bobbing in a sea of juice. All that liquid was originally trapped in the berries themselves, and you'd be boiling it mightily for a long time if you just threw the fruit and sugar together and tossed them on the stove.

But separate the liquid from the fruit, add a little lemon juice (which is rich in pectin), and--here's the trick-- cook down the liquid, not the fruit. By cooking the liquid by itself first, you can evaporate any excess water without exhausting the fruit's delicate flavors. There's also less risk of burning and sticking when you're just simmering juice.

This is a technique I first picked up from Helen Witty's invaluable, library-available collection, The Good Stuff Cookbook. In my copy, the jam chapter is wrinkled and spattered on every page, with annotations, additions, and comments in pen and pencil from years of messing around. I use a lot less sugar than Witty does, but her method (streamlined here) still works like a charm to produce delicious jams just thick enough to cling to your biscuit, redolent of ripe, sunwarmed summer fruit.

Since strawberries are ripe and wonderful this week, now's the time to grab a case of jars, a flat of fruit, and get your birthday-and-holiday gifts nailed down. I love Albion berries in particular, but Seascapes, Tristars and Chandlers, all varieties that do well in our cool coastal climate, won't do you wrong, either.

If you want your sealed jars to be able to sit around in the pantry, you need real canning jars topped with two-part lids. Otherwise, if you're just going to stick your jam in the fridge immediately and eat it soon, you can reuse any clean, cute glass jar you have. For best results, sterilize any jar in a boiling-water bath for 10 minutes before using.

Strawberry Jam

Ingredients:
4 pint boxes whole strawberries (2 1/2 lbs)
1 1/2-2 cups granulated sugar, depending on sweetness of berries
juice of 1 lemon, about 2 tablespoons

Preparation:
1. Rinse, drain, and hull strawberries. Slice in halves or quarters. In a nonreactive bowl, toss berries with sugar and lemon juice. Cover and let stand for 3-4 hours at room temperature or 6 hours to overnight in the refrigerator. Stir occasionally, scraping the bottom of the bowl to distribute and dissolve the sugar.

2. When sugar is dissolved and berries are floating in a bright-red syrup, pour into a large nonreactive pot. Bring to a frothy simmer, stirring frequently. Let simmer for 2 minutes, then pour back into bowl. Let cool. Cover and let stand for 2-3 hours at room temperature, or in the refrigerator for 6 hours or overnight.

3. Meanwhile, sterilize your jars, lids, and rings. Set a colander or strainer over a wide, large, and heavy stainless steel or enameled cast-iron pot. Pour berries into colander, letting all the syrup drip into the pot. Remove colander full of berries and set aside.

4. Bring syrup to a boil over medium heat, stirring frequently. Once syrup comes to a boil, stir and watch: it will move from what looks like a pot full of Kool-Aid to a seething, deep-garnet mass of thick, glossy bubbles. Dip a metal spoon into the syrup and let syrup drip off the side of the spoon; it's ready when the last few drops are fairly thick and sticky.

5. Pour in reserved berries. Bring to a boil, stirring constantly. If you'd like a thicker jam, mash berries lightly with a potato masher. Simmer for 5-8 minutes, until berries are translucent and mixture has thickened slightly. Scoop into jars and seal.

6. Set jars on a clean towel and do not touch or move them until they are completely cool. If you're using canning jars, listen for the slurpy sucking pop of the jars vacuum-sealing. Sealed jars will keep up to 1 year in a cool, dry place. If jar isn't sealed, store in fridge and eat within 2-3 weeks.
