for those of you who love asparagus :-)
It comes out thicker, more a mayonnaise texture, but am sure that could perhaps be rectified with a little boiling water, or more butter perhaps, am reheating my leftovers tonight, so will experiment.
To make it into bearnaise, add a couple of good pinches of dried tarragon.
3 rounded tablespoons creme fraiche (I use low fat)
1 teaspoon cornflour
2 egg yolks
3/4 tablespoon white wine vinegar
1/2 tablespoon lemon juice
2 tablespoons soft butter
Put all the ingredients in a small saucepan except the butter.
Whisk over a medium heat, until it reaches simmering point, and is thick.
Remove and taste, add pepper and salt if needed.
Whisk in the butter and serve,
enjoy :)
