Cooking Tips & Tricks

Here are some extra tips to keep things smooth in the kitchen:

• Use a fish fillet of even thickness so it cooks uniformly.
• Don’t skip chilling the assembled roll. It prevents leaking and gives better puff.
• Bake in the middle of the oven for even browning.

What to Avoid

Avoid these common mistakes and you’ll be golden, literally.

• Skipping the spinach drying step: Wet spinach makes soggy pastry.
• Overstuffing: Keep filling moderate to avoid bursting the crust.
• Using hot filling: It will melt the pastry before it even hits the oven.
