I just got some Meyer lemons at Costco to use for homemade limoncello. I started two batches, each of which required 20 lemons. After I peeled the lemons, I juiced them, and so now I have the juice of 40 Meyer lemons in my fridge. It's probably about seven or eight cups (I put it in the leftover vodka bottles but didn't measure it).
What should I do with all this lemon juice?
