re: I make a lot of sauces, which are your favorites to make and use?

I make a lot of sauces, glazes, and marinades, including many of those on the OP's list.

Love chimichurri sauce, pesto, and a good board sauce for steak. All have fresh herbs as the main ingredient.

I make a spicy sauce that i call "green stuff" which I serve over Pollo a la Brasa, but also goes well as a salad dressing.

I just made "hot honey", today. I've made it in the past, but didn't know it was a "thing" for putting on pizza. I used it as a glaze for chicken thighs. There's a lot of recipes for it out there. Its basically honey, hot peppers, and apple cider vinegar. Good stuff.
