Why bake without thawing?
Frozen su boregi is usually baked directly from frozen in a preheated oven. During thawing, the pastry may absorb excess moisture and lose the expected layered texture. The safest approach is to follow the package instructions and adjust time carefully by oven type.
Oven and service control
A golden top alone may not be enough; the inside should also be heated through. In professional kitchens, tray weight, oven load and serving time should be planned together. When served warm, the pastry texture and cheese filling are felt more clearly.
How to store leftovers
Baked pastry should not wait at room temperature for long. Leftover portions should be cooled quickly and refrigerated. For product details, see Frozen Water Pastry.
