After a minor excavation, I found Tdawg's protein shake blender. Pan (check), 3-4 cups pureed strawberries (check), lemon juice (check) and 7 cups of sugar. Do what?? Find glasses (check). Reread recipe (check). Yup, SEVEN cups of sugar! Egads! Well, I don't have seven cups of sugar. And I'm NOT going to my neighbor: "'cuse me, can I borrow seven cups of sugar?" So I use the 3 cups that I have.
Well, in hindsight, I should have used a bigger pan. We almost had a disaster. And I don't have a (candy) thermometer. So I guessed. Added the pectin and it was a foaming explosion. Waste not want not. So the mix (very hot) went back in the blender to de-foam. And then into containers.
All in all, it worked out ok in the end. Back to the store again (for sugar) and made a second batch. And we have lots and lots and lots of strawberry...well, not exactly jam. More like preserves/syrup. But it is delicious! I have been having it on my English muffins and it is killer on ice cream!
