We are right in the middle of the soup season. Let's open the season with a special onion soup. I'm sure you came across many onion soup recipes in your life but let me tell you guys- this one is different. I wouldn't expect apple cider to fit so well in this recipe. I know, I know, it's not traditional, but the fact that the cider I used for this recipe was produced from scratch by my friend Idan is a huge wow! The acidity of the cider plays the same roll as wine would do, and because this cider was fermented to zero sweetness it doesn't overwhelm the sweetness of the onion. This soup is perfect for cozy winter evening with your lover. Pair with your favorite gooey cheese and homemade sourdough croutons.
