We gave the cooked at home, ready beer battered, frozen haddock, from Lidl, another go today. Our third attempt, along with chips and mushy...
The first two attempts, oven cooked, it was fine on top, nice but the lower part came out quite soggy, cooked on a flat tray. Second attempt, cooked raised on the grill pan grid, resting on a tray. This time, I tried cooking, much higher from the tray, on one of those cake cooling stands. Much better, but still not quite there.
Next time, I'll try adapting one of those BBQ type grids, which clamps the food between it, allowing you to flip it over, without disturbing the food. One of those things with a handle. We already have one, but due to the length of the handle, it wouldn't fit in the oven. Cut the handle down, and it will be easy to just flip it part way through, and get it firm on both sides.
