1. Thoroughly grease an 8-inch round pan with 1 tablespoon butter.
2. In a large bowl, stir yeast into water to soften. Add flour, sugar, salt, garlic, potato, 4 tablespoon butter, and egg. Beat vigorously for 3 minutes with either a wooden spoon or a stand mixer (batter is too thick to use a handheld mixer). Scrape batter into prepared pan.
3. Cover with a tightly woven cloth, such as a dishcloth, and let rise for 50 minutes; after 40 minutes, preheat oven to 375 degrees F. Just before baking, sprinkle surface with cheese and dot bread with 2 tablespoons cold butter. Bake for 30 to 35 minutes, until internal temperature reaches 190 degrees F on an instant read thermometer; surface should be golden. Cut into eight pie-shaped wedges. Serve immediately.
