Stir together in a small bowl the warm water, yeast, and 1 teaspoon of honey. Set aside until bubbly, about 15 minutes.
In a large bowl, or the bowl of a stand mixer, mix together the flours, cornstarch, xanthan, and salt. Add the butter, warm milk, honey, eggs, and bubbly yeast mixture. Mix on medium for 1-2 minutes. Stir down the sides. Mix for 2-3 minutes more. Set aside and prepare the baking pan.
In a 13x10” pan, lay down a piece of parchment. Butter the parchment (or spray with an oil spray). Sprinkle lightly with flour.
Scoop the batter using a # 20 scoop or make mounds of batter if you don’t have a large sized scoop. The rolls should be just touching.
Use clean fingertips to smooth the tops of the rolls, making a flat top to each. Sprinkle with seeds and cover with cellophane. Set in the oven on bread proof or in a warm place for 1 ½ -2 hours.
When ready to bake, preheat the oven to 350 ℉. Remove the cellophane from the tray. Brush the top of the rolls gently with milk.
Bake in the center of the oven for 20-25 minutes. Add more milk on the top during baking, if desired. The tops should be golden brown.
