This recipe is really good with a few modifications for our family. The anchovy to garlic ratio could be adjusted in the anchovy butter which is really nice. I used 1.5 T garlic (5 cloves) to 4 anchovy fillets with olive oil and 4 basil leaves and chili flakes in the paste along with the butter. I marinated the steaks in 1/4 cup olive oil, with 1 T garlic, 1/2 tsp chili flakes, oregano, lemon juice, and zest. We Loved it; modify the recipe to suit your taste but the base recipe has it all!
Why ruin a yummmy old lamB shake with the anchovvy paste! YUCK
