Ingredients
Sauce: 2 egg yolks, 1/2 lemon juiced, 1 pack unsalted butter, salt and pepper to taste.
Muffins, brioche or a bread of your choice, slices of thick ham, 2 eggs.
Melt the butter in a pan and skim any white white residue which forms on the top, set aside but keep warm. Set a bowl over a pan of simmering water and add the 2 egg yolks and lemon juice, start to whisk continuously. The eggs will thicken up over the heat, once they have thickened (around 6 mins whisking) take the bowl off the pan and very gradually add the butter a tiny drizzle at a time, whisking thoroughly all the time. The sauce will start to become glossy and thick, if it gets too thick use a table spoon of warm water to thin it a little.
Once the sauce is ready, season to taste. Toast the bread, poach the eggs and then stack the bread, ham and poached eggs on plates and slather with the sauce.
