Time to roll out the red cartons — strawberries are in season. And local strawberries, especially those from my CSA farm, are a real treat to start the summer off with. If it weren’t for these bursting-sweet nuggets of bright red, I’d never be able to make this shake half as good. No “five dollar shake” with milk and ice cream for me, please. This one’s just milk, fruit, basil and ice.
