Chocolate and coffee – a match made in heaven. The roasted notes of the coffee give the chocolate a boost, a solid backbone, both perfectly accompanied by the rich flavour that comes from using dark brown sugar, packed full of molasses. To make sure both the coffee and the chocolate have their chance to shine, the two are heated together with the butter and milk, allowing the flavours to bloom. When choosing your coffee, you want to use something ground very finely, so the texture of the cookie isn’t gritty. And, if your instincts say this would be good with a little chopped chocolate added to the cookie dough, trust your instincts.
I started thinking about about the waste from coffee because in a restaurant people drink a lot of coffee; you can end up throwing away a lot of coffee grounds. We decided to start cooking with used coffee grounds, and the dishes we came up with tasted just as good - with a rich dark coffee - as they would have using fresh coffee grounds. Just store the ground in the refrigerator in a sealed plastic container with enough space for air circulation.
