Experimenting with decreasing the temperature will be the greatest way to resolve if it offers you the results you want. Aluminum is an effective materials for bakeware because it is a good conductor of heat, which leads to even baking, but the shiny surface of the aluminum might forestall proper browning. For finest outcomes, look for bakeware made from a heavy-gauge aluminum rather than thinner, flimsy aluminum. The thinner bakeware could additionally be cheaper but could warp when uncovered to excessive temperatures, causing uneven baking.
