1 kg butter
60g tomato ketchup
25g Dijon mustard
25g capers (in brine)
125g brown eschalots
50g fresh curly parsley
50g fresh chives
5g dried marjoram
5g dried dill
5g fresh thyme, leaves only
10 leaves fresh French tarragon
Pinch ground rosemary
1 garlic clove, squashed then chopped very finely
8 anchovy fillets (rinsed)
1 tbs good brandy
1 tbs Madeira
1 tsp Worcestershire sauce
½ tsp sweet paprika
½ tsp curry powder (Keens)
Pinch cayenne
8 white peppercorns
juice 1 lemon
zest of ½ lemon
zest ¼ orange

Method:
Mix all ingredients with the exception of butter in a glass bowl and leave
to marinate for 24 hours in a warm part of the kitchen (a slight
fermentation occurs). Purée the mixture in a blender and push through a
chinois. Foam the butter and mix with the purée. Cover and store in the
fridge. It is customary to form the butter into a log, freeze it and cut off slices as you need them.
Keeps for several weeks.
Upon service a round of frozen butter is placed on the cooked sirloin and put under a VERY hot salamander for just long enough to begin to brown the top of the butter (while the butter underneath stays cold).
