A friend needs to stop eating citrus and certain other foods (eggplant, tomatoes), and he is looking for a substitute for a lime wedge in drinks. Any suggestions?
Depending on the drink, something quick-pickled can provide a similar acidity: celery, cucumber, grapes.
When in Hawaii they use pineapple slices. Fun to eat afterwards to.
Pineapple is probably out, too because it is so acidic. Mint leaves, bitters, muddled raspberries...
If acidity is the issue, then maybe he can just add a drop of food grade lime essential oil to drinks?
