I moved to San Francisco exactly three weeks ago (a move that I will post about later!) and with the move came: TEMPORARY funemployment, closer proximity to Berkeley Bowl, and friends eager to learn about making jam (among many things). The combination of these three random things somehow resulted in homemade strawberry guava jam! It began when a friend and I went to Berkeley Bowl to where we let the produce inspire us. With strawberry season at its peak, we could not pass up the gorgeous bright red, cheap organic strawberries. But every jam needs pectin and strawberry doesn’t contain much so we looked for a tropical fruit that contained more pectin and chose guava. Thus our jam making journey began!
I weighed the ingredients I used because I prefer measuring with weight. Feel free to be loose about every measurement! Your jam taste buds may be very different from mine.
150 grams guava (about 3 medium sized)
368 grams (one small green tray that we overstuffed :P)
75 grams brown sugar
50 grams white sugar
~ 1 tsp. lemon juice
a pint-sized mason jar
Remove some of the seeds from the guava. I like to keep a little bit of the seeds because the fleshy part of the guava where the seeds are attached is sweet and pulpy. It’s also fun to bite into seeds sometimes.
Then take a small pot and put the sliced guava in it. Fill the pot with just enough water to cover all the guava. Let it boil. Then lower the heat and simmer the pot uncovered for about 20-30 minutes or until most of the water is boiled off and the guava is mushy when poked with a fork. Mash it up real nicely while leaving a few chunks. It should look like this:
While letting the guava boil, fill another pot with the strawberries. Simmer it covered for about 30 minutes or as long as it takes for the strawberries to release its juices. You can add the lemon juice now if you want or omit it altogether.
Once the strawberries have released a good amount of juice, crank up the heat to medium high and add the sugars. Let it boil for a few minutes while stirring frequently. Add the guava. Let it boil for a few more minutes and allow for the whole mixture to come together. Once you like the consistency of the jam (which depends on how much of the liquid you boil off), turn off the heat. It should look something like this:
(Sorry for the poor photo quality!)
Once the jam is done, put the hot jam in the sterilized jar***. I let it cool for a bit before refrigerating and enjoyed it once it was cool.
Jam making success! (:
***NOTE about canning: I am no expert on proper canning technique. BUT I did sterilize my jar by placing all of its pieces in a large pot of water, boiled it for 30 minutes and took it out with tongs right as my jam was ready to go in. Use a hot jar for hot jam!
