It's been 85 degrees (F, not C, thankfully!) indoors in the shade here, which to my San-Francisco-Bay-acclimated system, feels quite unpleasantly hot. Luckily, there are things one can do to combat this:
Basic Frozen-Fruit Smoothie:
Fill a large glass with frozen fruit of some sort
Fill the interstices between the frozen fruit in the glass with milk
Dump the lot into the blender and puree until no longer chunky
Today's version of this was 2/3rds of a glass of mango, and the rest blueberry; it turned out quite deliciously well. My more usual versions involve just berries (since those are what's common in the store), but I think I'll have to try the mango more often; it makes a nice sort of base to offset the berries.
