Hello all. Last Sunday, I attempted a lemon butter sauce (don't laugh -- though I'm an expert eater, I'm a novice cook!) The recipe called for white wine, white wine vinegar, minced garlic, butter, and lemon. As the wine, vinegar, and garlic were reducing on the stove, all of the garlic pieces TURNED BLUE!! Everything else worked out perfectly - the finished sauce had a great consistency, color (except for the weird little blue chunks of garlic) and taste. I thought about straining out the garlic, but it was just my sister and me eating, so I didn't bother. The recipe didn't mention anything about color changes. Why did this happen? Did I make a mistake? Anything I should do differently next time?
