Citrus fizz

I would say that this recipe is a bit of citrus overload, but then again I don’t think there’s any such thing. I sometimes have to restrain myself from cramming citrus ad infinitum into whatever I cook. I’m like a kid in a candy store with citrus, except to render that simile exceptionally bland, the child is very sober and restrained and the candy store is just the local fruit & vegetable store with its not amazingly diverse citrus range.

This recipe is adapted from the latest issue of Delicious, and originally called for six Meyer lemons. Having precisely zero Meyer lemons handy, I changed the recipe to involve input from lemon, navel orange, Emperor mandarin and ruby grapefruit. The fizz element comes from the addition of yeast, which reacts with fructose and glucose (which is produced from the sucrose in the sugar courtesy of the yeast enzyme invertase — ok, wanton science indulgence time is over now) to produce carbon dioxide and alcohol. So the mixture should be slightly carbonated and ever so slightly alcoholic, although the relatively short reaction time really keeps this minimal. I find that the carbonation is barely detectable really, except as a slight change in taste (since carbon dioxide has a faintly sour taste) but it’s a pleasant and interesting change rather than just having this be your standard jug o’ juice.

It takes a little while to prepare, but in all it’s not much effort and it’s worth it in the end.
