Prepare your NOMU Scones as per the instructions on the box, mixing in the chives and grated cheddar into the mixture just before cutting and baking.
Blend the egg yolks in a blender or processor until well mixed. In a small saucepan, heat the lemon juice and vinegar and, with the motor running, add the heated lemon juice/vinegar in a slow thin stream to the eggs until well combined.
With the motor still running, very slowly add the warm melted butter to the egg mixture. The slower the better! Once it is thick and you've incorporated all the butter, season with salt, pepper and a generous pinch of NOMU Smoked Sweet Paprika
Using a deep saucepan, bring your water to a boil. Add vinegar to the water. When you are ready to poach your egg, reduce the heat so that the boil subsides but medium sized bubbles continue to rise to the surface.
Crack an egg into a teacup and with a wooden spoon create a whirlpool in the water and gently slide the egg into the centre of the swirl. Turn the heat down and gently poach for 3-4 minutes. Use a slotted spoon to carefully remove the poached egg from the water and place on kitchen paper to remove excess liquid.
Trim any excess untidy white around the poached egg with a knife. Cover to keep warm.
Fry the chorizo in a saucepan until they're sizzling hot, and while the eggs are poaching, toast your scone halves to heat them through then lather with butter.
Place a few slices of the sizzling chorizo on top of each scone half. Top with a poached egg, followed a generous dollop of hollandaise sauce and a sprinkling of Sweet Smoked Paprika. Garnish with finely chopped chives and serve immediately.
