Cheese
My daughter and husband bought me a book on home cheesemaking for Mother's Day this year. Ada was most insistent that it was the best possible present for me, after my attempt to show her how rennet worked failed a few weeks back (I overheated the milk, judging by the cheese book's advice).
I now have 500 mL of mascarpone in the fridge, and I'm not quite sure what to make. We've eaten about 150 mL already. Somehow, I wasn't expecting quite so much from just 2 L of milk and 300 mL of cream.
