Since the material a baking tray is made from determines how quickly it conducts and holds heat, the same recipe can turn out differently on different trays. That is why the baking time given in a recipe may need adjusting depending on which tray is used.
How do metal trays behave?
Metal trays conduct heat quickly, which is an advantage for recipes like cookies and poğaça that bake fast and are meant to come out crisp on the bottom. Dark-coloured metal trays absorb more heat than light-coloured ones, which can shorten the baking time further.
Anything baked on a metal tray can brown faster than on a light-coloured one, which is why it helps to lower the oven temperature a little or shorten the baking time when using a dark tray.
What difference do glass trays make?
Glass trays absorb heat more slowly than metal but hold onto it longer once absorbed; that quality makes them a good fit for slow-baking dishes like casseroles and güveç. Because glass releases heat slowly, food can keep cooking for a while even after it comes out of the oven.
Recipes baked in glass usually take a little longer than the same recipe in metal, so it can help to add a few extra minutes to the time given in a recipe when using a glass tray.
What is the advantage of a stone baking tray?
Stone trays are the go-to for recipes like pizza and bread that need a crisp base; stone holds heat evenly even at very high temperatures, helping dough cook evenly on the bottom. A stone tray needs to be preheated along with the oven, or dough placed on a cold stone will not crisp up the way it should.
Stone trays are fragile and need careful handling around sudden temperature changes; rather than placing a cold stone tray directly into a hot oven, letting it heat up gradually alongside the oven is the safer approach.
How do silicone moulds differ?
Silicone moulds conduct heat much more slowly than metal or glass, so recipes baked in silicone usually take a little longer and brown less noticeably. Silicone's flexibility, on the other hand, makes it easy to pop the finished product out of the mould.
Silicone moulds are especially popular for cakes and muffins; anyone after a crisp exterior, though, will find silicone gives a less successful result than metal or stone.
Which tray should be chosen for which recipe?
Metal or stone suits recipes that need a fast, crisp result, while glass suits ones that call for slow, even cooking; silicone is chosen mainly for how easily it releases the finished product. Keeping more than one type of tray on hand gives more flexibility across different recipes.
The surface matters as much as the colour; perforated metal trays improve air circulation, particularly for pizza and some breads, helping the base brown more evenly. Flat-surfaced trays are a more practical choice for batter-based recipes like cakes and tarts.
Non-stick trays cut down on the need for greasing, but it is worth remembering that the coating can wear down over time with prolonged use at high heat; using silicone or wooden tools instead of metal spatulas on a non-stick tray helps it last longer.
