A combo of classic American dinner roll with Japanese milk bread recipe. These are super chewy and soft, brushed with butter and egg whites. Not to mention these are also super easy to make!
Mix all ingredients except butter until everything is well incorporated in a stand mixer. (You may need to add more flour or water as different bread flour are a bit different in terms of water retention). Put in butter and let it mix for another 10mins. Let it sit for 1-2 hours until it grow in 2x the size. Form into small dough (ball shape), apprx 60g per each. Brush with egg wash. Bake at 375F for 20min until brown on top.
