This is a killer condiment which I’m sure will enhance all sorts of things. It was invented in Geneva, presumably at the Café de Paris, and I believe its original use was for steak. I used it to liven up some frozen cooked lobster, a task it performed admirably. I’m planning to use the leftovers on some grilled mussels for tapas. You can of course freeze leftovers in handy-sized chunks.
The list of ingredients is long, but many of them are items you have on hand anyway (at least, I do). And with a food processor it’s quick to put together. I’ve listed the herbs I used, but you can vary them according to what you have on hand/what you like. If using on steak, a teaspoon of mustard might be a nice addition. Whatever you use it for, the idea is to put it on your chosen food in slices about 50mm thick, and then grill it for a few minutes to melt and brown it.
