Zenker Glass Fibre Silicone Quiche Tray 5 "FEEDBACK FROM MALLORCA" Mrs Douglas 10 September 2019 ONE WORD FANTASTICO! received my Zenker Glass Fibre Silicone quiche Tray here in Mallorca, and used it today for first time, making a quiche. Results wonderful, crust was crispy on sides /bottom, no soggy underdone base, exactly as the product states! as recommended as cooking is more quicker, was perfect. No difficulties quiche out of tray, when slightly cool put a plate on the top, turn it over, just falls out of tray, and turn it over again. Cant wait to use my Muffin Tin trays.
