When I bake these buns the first time I wrote down “Taste and crumb are perfekt, but the crust shows cracks. Maybe proofing was to short –> Problems with yeast? Try again!” When baking the buns for a second time with a fresh yeast batch I realized that it was no problem with yeast but the rolls just need their time. And the baker needs patients. And so I elongated proofing time considerably and baked the rolls when fully proofed. And then the rolls are perfect: Fluffy crumb, tender crust and delicous flavour with notes of potato and butter.
I served the rolls once again with my favourite vegan burger patty. I still tend to try new bun recipes but stick with the patty. And so the variety of recipes is quit big. I marked all bun recipes with the tag Burger (<- click) to make finding more easy.
