Serves 2-4. Historically this worked beautifully with grilled beef or lamb, and a bit of salad . Might work with grilled Halloumi
50ml brandy 
8 black peppercorns 
12 green peppercorns (the ones sold in brine) 
3/4 of small tub of creme fraiche 
1 tsp tomato puree 
1 tsp Dijon mustard 
5-10 blades of fresh tarragon (depends on how strong it is) 
- Throw black peppercorns into small saucepan and dry fry for a minute 
 - Add brandy, green peppercorns, and 3 blades of finely chopped tarragon. Boil hard so that the brandy reduces by two thirds 
 - Turn the heat down and add tomato puree, creme fraiche, and two more finely chopped tarragon blades. Heat very gently, but don’t allow to boil 
 - Check if more tarragon is needed. Finally add mustard. Allow to sit for 10-15 minutes for flavours to infuse
