Jerusalem artichoke and mushroom dauphinoise

This is almost sexy in it’s unctious creaminess!!
Make sure the artichokes are tender when you cook them, because when I cooked this the first time, they weren’t!

1 1/2 lbs Jerusalem artichokes (or sunchokes)
2 tbsp olive oil
1 sliced onion
2 crushed cloves of garlic
5 cups cremini mushrooms, sliced
1 cup creme fraiche or sour cream
2/3 cup light cream or whole cream
1 tbsp whole grain mustard
1 good pinch freshly grated nutmeg
1 lemon, grated zest only
1 heaped tbsp chopped fresh parsley
3/4 cup grated gruyere cheese

Preheat oven to 350 degrees
Cook artichokes in lightly salted boiling water for 15 minutes or until tender.
Meanwhile, heat 2 tbsp olive oil in a large pan. Add 1 sliced onion and 2 crushed cloves garlic and saute for 3 minutes until soft.
Increase the heat and add the sliced mushrooms and cook for 5 to 10 mins tossing occasionally, until golden.

Drain the artichokes and refresh under cold running water. Drain again and peel.
Slice any large artichokes into thirds and arrange in a shallow 1 1/4 quart dish with the mushroom mixture.

In a bowl mix together the sour cream, (or creme fraiche)  light cream, whole grain mustard, freshly grated nutmeg, grated zest of a lemon and chopped parsley. Season well and pour over the vegetables.
Sprinkle the top with the grated gruyere cheese and bake for 30 to 40 minutes until golden and bubbling.
Serve immediately.
