There's nothing a cook likes better than to hear a good, "Ahhhhhh."
It's even more satisfying when inspired by such ordinary fare as your standard burger bun. That's what happens when you channel your inner artist and paint risen dough with a rather curious mix of yeast, rice flour, sugar, water and oil.
The coating generally is called Dutch Crunch, mostly in the United States, and especially in San Francisco. Yet in the Netherlands, where the coating popularized by northern European bakers was particularly favored, it's called tijgerbrood or "tiger bread." Go figure.
The name is even more inscrutable given that the baked crust's mottled effect looks more like the pelt of a cheetah or giraffe.
We're going with Dutch Crunch, because that name also conveys the crust's slight crackle, which adds another nuance to a well-filled bun.
The origins of Dutch Crunch topping are murky. Breadmaster Peter Reinhart revived the topping in his book "The Bread Baker's Apprentice," where he used it on loaves of Vienna bread. Rice flour (white or brown) is the main ingredient, but you also can use Cream of Wheat cereal. (We used Bob's Red Mill rice flour, available in many groceries and co-ops.)
We'll be honest: The coating might remind you a little of a papier-mâché project. Then again, this is kind of like art.
Here, our basic bun recipe gets an extra boost of flavor by swapping in potato flakes for some of the flour.
