A favorite breakfast. Homemade raspberry-blackberry preserves on bread.
I've been working all summer on ways to enjoy the food when we have it, as well as ways to prolong that gorgeous rush of flavor well after the ground is frosty and dusted with snow. The gorgeous bolero carrots that Siena Farms includes in the CSA boxes will last for quite awhile, but other veggies won't. Like Cynthia, I froze things that are waiting for mid-winter debut. I also baked things to outlast their normal shelf life and I've flirted heavily with canning and preserving. I'm a small-batch gal when I'm trying to puzzle out the proper how-to, so most of what I pickled was eaten right away. The jam I made, though, should see us through part of the harsh of winter with a welcome jolt of flavor. We do all get tempted to eat it straight out of the jar with a spoon, though, so I hope it lasts a while.
Good jam on good bread is one of my constant cravings. When it's good, it's like a sunburst in the middle of February. When I finally snapped out of denial that summer had turned to fall, I knew that I had to make some of the fruit flavors last.
I've been fascinated with jam for a long time. Surprisingly, I hardly had any truly good jam until I was 10 or 11. Until then, I preferred jelly and I thought of it strictly as a component of the PB&J…until one fateful jam- and marmalade-filled trip. I went on a ski trip to a small Swiss village with my classmates and each morning at breakfast we were served continental breakfast. Every table had big bowls of jam and marmalade to spoon on top of toast.
Quite possibly, it may have been the first time I didn't put butter on my toast—just jam. It tasted like…fruit. I couldn't believe it. And this was even vaguely institutional jam—you just knew the chalet had outsize jars of the stuff in the kitchen next to the 3-gallon mayonnaise and a container of more capers than most people use in a lifetime.
Still, that non-fancy jam began a culinary quest that I'm just now fulfilling. On that trip, I filled up on bread (and marmalade) and left the ski trip with a deep love—not for the swift downhill and our instructor Antoine—but for blood oranges, vol-au-vent, and jam that tasted like sweet fruit instead of just plain sweet.
For years, I've harbored dreams of making marmalade (a task I will finally tackle this winter—stay tuned) and jam. Jam is a little scary if you've never done it before. But who ever let being scared stop them?
A couple of things finally got me stove-side and actively experimenting.
First of all, I spend a lot of time thinking about food traceability. I like to support local farmers, so I like it when good food comes from local sources. Still, I want to know about the sources and quality that goes into food, no matter where it comes from. I might buy a jar of jam from France, but I want to know where the ingredients come from and like them as much as the finished product. When local sources hold their own against anything else available, I feel excited and proud—and in my corner of the world, I luckily get to feel that way pretty often.
Secondly, that jar of jam from France that we've loved is now a dizzying $19 a jar. It used to be an affordable $7 indulgence. It's kind of hard to enjoy the fruit and flavor in the morning when your brain—without your permission—is tallying what that second piece of toast does to your monthly food budget. I firmly believe that one should never be meagre when offering guests (and yourself!) something delicious, so I dislike what that financial turn does to the taste pleasures. (Boo, exchange rate and recession. Boo.)
Thirdly, if my efforts can rival that lovely jam, I would slash our breakfast and elevenses carbon footprint if I use mostly local produce. The carbon footprint might not have a flavor of its own, but it can surely affect the enjoyment of a meal. I'm totally OK getting imported food (and I do), but if I can best the quality in my kitchen, hurrah! I knew it was finally time to try.
Finally, I have a 3-year-old who does not eat fruit. Except bananas. (Have you ever heard of such a thing?) However, she does eat jam. I want to share all kinds of pleasurable jam flavors with her so she can taste the real fruit in a way that she likes. It's kind of like a gateway food. (A gateway to 7 servings a day, kiddo!)
To move on my jammy goal, I took a class at Stir and Chef Molly Loveday walked us through several jams from Christine Ferber's book "Mes Confitures." I can read about jam all I want, but sometimes you need to see it happen right in front of you. Stir is my favorite place for that, because the food is awesome, the space is small enough that you see every little detail, and you can ask endless questions (which I often do). I never had a grandmother who made jam, so I had no context in which to place the instructions I read. I needed a place like Stir to see all of the color changes, textures, reflections, and processes. (By the way, you should totally go there.) The basic take-away: Just get in there and do it. Use great ingredients, decide for yourself how sweet it should be and do it. Quit being so scared.
I also went to an afternoon tea hosted by Edible Boston and D2E at Upstairs on the Square where their guest Eugenia Bone, author of Well-Preserved, discussed canning, jams, jellies, and preserving in general. She made several great points about why it makes sense to do it and what affect it has. The basic take-away: If you take a moment to make your own tomato sauce or jam, you can use local ingredients. You take that part of your pantry and make it local (or organic or whatever aspect is important to you). You have greater control over the source of your food and who you support with your spending. Small batch preserving is easy to do, takes very little time, and you don't have to set aside an entire day—the process of filling your pantry is calm and goes on all season long.
I dream of that kind of low-key approach. So far I've made several jams, but nothing in a quantity that requires "putting up." It turns out we want to eat it all right away, but luckily jam lasts a long time, thanks to sugar and heat. (Just think of how long that jam in your fridge has been there.) I've been working in small batches to refine the process and take advantage of a small amount of gorgeous produce. I'm still working out some kinks, but I've had some stellar successes.
I've followed Eugenia's advice a few times and just made jam with what was around and good-looking, but using Stir's technique. I had strawberries that were in danger of going bad but oh so fragrant, so I chopped them and cooked them up one night. We ate the jam for breakfast the next morning to cheers and applause, and second helpings.
The superstar jam, so far, is based on a recipe from Christine Ferber's book that we made at Stir. It's raspberry-blackberry preserves and it's so good. No, even better than that. I bought all the raspberries and blackberries that Formaggio had one day and went to town making a jar of lovely preserves.

Raspberry-Blackberry Preserves
I put the raspberries through a food mill to make them a liquid. I cooked the raspberry liquid with the whole blackberries and the sugar (50 percent of the fruit by weight). The bright red liquid coats the blackberries, making the deep berries glow a sort of luscious red when the light catches it. It gels up to the perfect thick jam consistency—exactly what you'd like if you were buying a favorite in a store. Everything about it is perfect…except that I only made one and a half jars. The half jar is already gone!
I've used this basic method for peach-nectarine-vanilla jam, pluot jam, strawberry preserves and a few others that have been greedily and happily devoured.
Basic Jam
- Buy yummy fruit that is almost luminous. The kind that you need to eat and distracts you from tasks at hand.
- Wash it very gently and cut it up or purée it.
- Give in this once and taste it to see how sweet it is. Stop yourself so you don't eat it all.
- Weigh it so you know how much sugar to add.
- Add sugar that equals somewhere between 40–60 percent of the weight of the fruit. The sweeter the fruit, the less sugar.
- Boil it while stirring. Use a candy thermometer to tell when the temperature reaches 220 degrees F. The books all talk about the jam flaking off the spoon in sheets, but I've found that happens before 220 degrees F. I don't know what that means for long-term storage, since I'm still figuring this all out.
- Pour it into sterilized jars and lids and process in a way that you agree with. Do some research because NO one likes mold, sliminess, foul odors or Botulism. Seriously, there are 5 million books and websites each with slightly different techniques. I'm still learning, so I don't have a good feel for the exact one I want to recommend.
The kinks I'm still working out are how to know how much jam a certain amount of fruit will become. Also, it's very difficult to reach 220 degrees F if you don't add a lot of sugar. A couple of batches have tasted like the sugar caramelized—which ended up tasting wonderful, but it wasn't what I was trying for. I noticed that for the batches where I added slightly more sugar, it reached 220 degrees with no problem or prolonged (caramelizing) cooking.
Anyone have tips for the sugar ratio that lets you reach 220 easily but doesn't overpower the fruit with sweet?
