Little potatoes are at their best right now – so try to think of any excuse to make use of them. Sauce vert is a classic French sauce of mayonnaise that has had a little crème fraîche and gentle herbs stirred through it. It is lovely dolloped on top of a bowl of warm potatoes.
Basic recipe mayonnaise
1/2 tbsp Dijon mustard
1 small bunch of chervil, leaves only
1 small bunch of chives, very finely chopped
1 small bunch of tarragon, leaves only, finely chopped
2 heaped tbsp of crème fraîche
1kg/2lb new potatoes
Place the mayonnaise in a bowl and simply stir in the mustard, herbs and crème fraîche. Steam the potatoes until they yield to a fork, divide them among four plates, then spoon the mayonnaise over them just before serving.
