This sauce works well with any vegetable, plus you do not need to use nuts. Chives, tomatoes, parsley and mushrooms all work really well. It’s also a lovely sauce to serve with poached fish or chicken. The secret is to reduce the vinegar and wine until you have a nice syrup consistency. The whisk in the very cold butter in small amounts and it will thicken nicely.
