Hashes and Toasts

Ingredients

Directions

Select only good quality meat, discarding any hard or gristly bits.
Slice the lean meat thinly across the grain and chop the fat into very thin pieces.
Chop all ingredients together until finely minced, avoiding large chunks.
Ensure your stew-pan and chopping bowl are thoroughly clean.
If using meat juice, ensure it is sweet and remove any fat and sediment; add a little fresh butter if the meat is lean.
