This is awesome with bacon wrapped scallops Works well with salmon too.
Juice from 1 lemon
3 cloves garlic
1/2 tsp salt
1/2 tsp dry mustard
1 tbsp fresh dill, finely chopped
3/4 cup olive oil
Leave all ingredients out so they're at room temperature. Combine first 6 ingredients in a food processor. Blend thoroughly. Slowly drizzle in the olive oil. You don't want to do this all at once. Take your time; it should be a thin drizzle. once thoroughly combined, put into a container and refrigerate.
