As evident from the title, I love tangy, even sour, flavors. After large meals, I peel a lime, halve it, salt it, put the halves together again, chew, and swallow. Very meditative. I snack on tamarind (not the sweet kind, of course) as often as I can. The vinegar/citrus to oil ration in my vinaigrettes is way off, nearly half and half. And I add mustard. And I love tangy pickles. I actually prefer plums under-ripe.
If you know of any recipes, or just ingredients, fresh or processed (e.g. a premade sauce), that you think fits the sort of flavor profile I'm after, please share, and I'd be grateful.
