1/2 pound smoked salmon or trout, skin and bones removed
2 tablespoons sour cream or creme fraiche
1 tablespoon lemon juice
2 tablespoons unsalted butter, at room temperature
Finely grated zest of a lemon
2 tablespoons minced chives or parsley
About 2 teaspoons prepared horseradish, or to taste
Salt and black pepper to taste
Pickled mustard seeds or trout caviar (optional)
Break up the trout salmon and place in bowl, along with the sour cream, butter, lemon juice, lemon zest and chives. Use a heavy fork to mash everything together. You want a rough spread, not a smooth pate. Add more butter if the rillettes look dry.
Add salt, pepper and horseradish to taste.
Cover the rillettes with plastic wrap and set in the fridge for an hour or so before serving. Spoon over some pickled mustard seeds or caviar when you serve.
Once made, pack the rillettes tightly into jars; try to get as many air pockets out as you can. Once packed, melt some butter over the top of the rillettes, cover and store in the fridge. It will keep for at least a week this way, and up to 2 weeks if you keep resealing the butter cap between each use. You can also freeze the finished rillettes for several months.
