For the last year or so i have cooked my yorkshire puddings in the halogen oven and it works well and when you only need a small amount of puddings this is a fantastic way of cooking them.
The yorkshire pudding batter i use is based on the 1 cup of each ingredient recipe which is ratio based again when you only want a 4 puddings this mix is perfect
My halogen and the silicone ramekin moulds i use can be found on my Amazon Shop linked here https://www.amazon.co.uk/shop/julesthelazycook
