1- In a saucepan, melt 20g of butter then add your shallots, sweat gently for 2 minutes then add your mushrooms, liquid cream, white wine, salt and pepper and cook for 8 minutes.
2- Meanwhile in another saucepan melt your 30g of butter then pour in the flour, stir and let cook gently for 2 minutes then remove your saucepan and let cool this way.
3- Here the 8 minutes of cooking are finished, pour your scallops into it, just bring to a boil then remove from heat, cover and let "infuse" this way for 5 minutes (flavor absorption).
4- Then drain your scallops into a bowl then gradually mix this cooking liquid removed into the roux which will have had time to cool* return to cook on the heat while stirring, test the seasoning then pour your scallops into it then add the diluted yolks and just bring to a boil while stirring well and remove from heat.
5- Remove your baking sheet from the oven, arrange 4 small piles of coarse salt then in each shell equally distribute your preparation,
Place then in the middle of the oven in grill position then as soon as they are gratinéed remove your baking sheet with care and place your shells on pretty plates also garnished with a small pile of sea salt.
You can prepare this recipe entirely the day before you will reheat it gently and you will then add the yolks to it.
*When you bind a sauce: either the roux is cold and the liquid hot or the opposite hot roux and cold liquid, by practicing this way you will never have lumps again.
We tasted them with an excellent white burgundy 2022 from Domaine des quatre saisons.
