Chiang Mai’s creative Flour Flour bakery has ventured into Bangkok with a shop dedicated to bomboloni. Don’t expect light and spongy donuts; here, they go in for buttery dough made using a homemade sourdough starter, which is left to ferment for 18 hours resulting in a dense texture. Try it out in their best-selling vanilla cream donut (B69), which looks almost like a Gram pancake, or opt for a set of all six flavors—cinnamon, lemon meringue, kinako soy, salted caramel, vanilla, and dirty chocolate—for B350. Be sure to get there early, as they're already in the habit of selling out within an hour of opening. They also serve coffee (from B55), with special combo deals like B100 for a latte and a cinnamon donut.
