Melt the butter in a saucepan and, once foaming, add the flour and stir well to form a paste. Cook for 30 seconds to 1 minute until bubbling. Gradually whisk in the ale until you have a smooth thickish sauce then let it bubble for 1 –2 minutes.
Add the cheese, crème fraîche, mustard, Worcestershire sauce and some seasoning and stir until melted and combined. Set aside to cool and firm up a little.
Heat the grill to medium. Lightly toast the bread then spread the gooey cheese sauce thickly onto one side of your slices of bread. Pop under the bread slices under the grill for a couple of minutes under a medium heat, or until golden and bubbling.
Meanwhile heat a little oil in a frying pan. Once hot crack in three of the eggs and fry until the whites are set but the yolks are still runny. Remove from the pan and repeat with the remaining eggs.
Pop the fried eggs on top of the roasted cheese then grind over some more black pepper to finish. Serve with pea shoots or green salad leaves. It makes for a beautiful lunch!
