Happy Marriage Rhubarb Jam Tart with Whipped Skyr
Called Happy Marriage cake in Iceland, this tart-like dessert is made with a rolled oat dough that doubles as both the tart shell and the crumb topping. Any leftover rhubarb jam is great spread on toast. It’s accompanied by whipped skyr, Iceland’s creamy yogurt. Slideshow: More Fruit Tart Recipes
