This is the summer of the onion in the Blocko house. We can't seem to get enough of them. Every time we grill I've been slicing up a few to eat on the side. Even Blockette likes them. When we grill them they get all nice and charred. Mrblocko and I fight over the blackest ones.
Naturally, when I came across this recipe I couldn't pass it up. Sweetened caramelized onions? Oh yes Please! I made a half batch, and this was enough for 4 burgers. You might get more servings if you aren't onion freaks like we are! Below is a full recipe.
Caramelized onions from Cherry on a Cake
6 large yellow/brown onions, sliced finely
4-5 T oil
4 T balsamic vinegar
2-3 T brown sugar
2 knobs of butter
salt to taste
Heat up the oil in a large skillet. Add onions and toss to cover with oil. Reduce heat to low and let onions cook slowly. Stir occasionally to prevent burning. This will take around an hour. When the onions are pale gold add the balsamic vinegar, butter,sugar and a good pinch of salt. Mix well and let the onions brown further. The sugar, butter and vinegar will help darken and caramelize the onions. As it begins to get darker make sure you stir more often to prevent burning and even browning. The onions are done when they are a dark golden brown color.
