Gather your tools and ingredients together
Zero your scales with the jug on it. Crack both eggs into the jug and note the weight (approx 100g for 2 medium eggs)
Add the equal weight in flour
Add the equal weight in milk (Soya, Oat, semi skimmed etc....)
Whisk until smooth and lump free
Add the same weight of milk again and mix till smooth
Leave the mixture to sit for 15 mins, or until you need it
Spray the bun tray with oil, inside each bun place (they probably have a proper name) and across the top.
Place the bun tray in a hot oven for 10 mins at around 200C, (or whatever the roast is finishing off at)
Stir your rested batter to ensure that it hasn't all sunk to the bottom. Take the HOT! bun tray out of the oven and lay it somewhere flat. Quickly pour the batter to fill each bun place and carefully place it back into the oven (trying not to spill it over the edges).
After approx 20 mins the Yorkshires Should be well risen, crisp and browned
