Double Cream de la Gruyere is an amazing thick cream from Switzerland. Hard to source but since it is usually/often shelf stable, worth stocking a few if you find it.
Yes, it's this thick. A classic use is as a dessert ingredient. Simply a splat of this cream and a handful of crumbled hard baked meringue. Sounds dumb but it's ethereal, rich and not too sweet.
But also an incredible cooking ingredient. Like scalloped potatoes. (Pommes Dauphinoise)
