watercress sauce

This peppery watercress sauce can be served either cold or warmed through - it's ideal with any white fish and very simple to make.  It's a great source of vitamins as well as being extremely tasty. 

You do need a blender or food processor though - either a liquidizer or a stick blender - to mix the ingredients.

It's excellent warmed through to serve over any plain grilled or fried fish.

Do not heat too much as it could curdle, just a gentle heating in a pan on the stove - don't be tempted to microwave it as the result could be the same.

It's a brilliant green colour - it looks very good against the deeper colours of salmon - quite dramatic. Just look at the photo here and imagine that spooned over the middle of a nice piece of salmon fillet.



Watercress Sauce
2 bunches of watercress
5 floz (150ml) soured cream
few twists black pepper
squeeze of lemon juice

Put all the ingredients into a blender and whizz together until smooth. Taste and season accordingly.

You can just pop this into a pan and warm through gently to serve over cooked white fish or serve it cold - I prefer it warm.

You could substitute spinach (about 8 oz, blanched before processing - just dip into boiling water for about 2 minutes) for the watercress.

I would serve this with salmon, trout or any white fish and some plain buttered vegetables and my old favourite, new potatoes.

In season, asparagus would be lovely, but petit pois, broccoli, cauliflower or carrots would be excellent.

Cook's Notes

This sauce can be prepared in advance up to the heating stage. 

Make it the day before even, but you must keep it refrigerate as it has fresh cream as one of the ingredients. 

Likewise, if you have leftovers, then keep them in the refrigerator, but I would not warm it again, just serve it cold - the heating and reheating processes are what cause bacteria to grow
