When you're buying a mango, pick up one in each hand and see how they feel. The heavier they are, the juicier, and if they've got soft, firm skin and a sweet smell, take 'em home. If all the mangoes in the store are rock-hard, buy the heaviest one and take it home to ripen in a cool place. Look for ready-to-go shrimp done up for shrimp cocktail at the fish counter (check the deli counter, too) of your grocery store. Know How: Roll limes (or oranges, or lemons) under your hand on the countertop before you cut them in half and juice them - you get the most juice that way. We love the convenience of canned beans, but not the salty goopy stuff that clings to them. That's why we always dump them into a colander and run under cold water before using them.
