The Best Strawberry Jam.
So what makes this strawberry jam the best? Well, it is just strawberries, sugar and lemon juice, so nothing gets in the way. If you have ripe, sweet strawberries, this is the real deal. And we use a technique that makes the process much, much easier. If you like jam, but don’t like all the specialized gear and the huge tub of boiling water, we have a solution: the oven.
It turns out you can sterilize your jars and lids in the oven, You can process the jam, too. (Just make sure your oven is true to temperature, they often are NOT, use an oven thermometer to be sure). Simply place your clean jars and lids on a baking sheet and heat in a 250 degree oven for at least 30 minutes. Remove the jars from the oven when you need them. Then fill the jars with jam, leave a 1/4 inch of room, wipe the rims clean, place the lids on, seal them and put the jars back in the oven for 15 minutes. Then take the jars out of the oven and they will seal as they cool. So. Much. Easier.
The other fuss about making jam usually has to do w/ pitting and skinning fruit, or in the case of strawberries, hulling. There are specialized hulling tools, but we use strong plastic straws (flimsy won’t work here) and run them from the bottom through the center of the strawberries. It is the fastest way to hull the strawberries, and something anyone (read, your kids or guest) can be dragooned volunteer to do. It’s almost fun, and you can snack on a few berries along the way.
As for the jam, we adapted the recipe (and the oven technique) from Blue Chair Fruit Company in Berkeley. Blue Chair has fine jams and marmalade, gear, classes and one of our favorite cookbooks. Worth a visit.
