Make the beer onion jam
Roughly chop the onion.
Heat the olive oil (2 tsp) in a small saucepan and once hot add the onions. Cook the onions for 10 minutes on a low heat, stirring them regularly to ensure they don't burn.
Add the Treason (240ml), apple cider vinegar (1 tsp) and sugar (2 tbsp) and mix. Simmer for about 20 minutes until the beer has reduced to a jammy consistency.
While the jam is simmering make the burgers
I cooked my burgers in the oven but you can also cook them under the grill, in a frying pan or on a BBQ.
Pre-heat your oven to 220ºC/200ºC fan.
Put the beef mince into a large bowl. Add the other burger ingredients (60ml Treason West Coast IPA, 1 tsp cayenne pepper, 1 tsp paprika and ¼ tsp salt). Using your hands, mix the ingredients together until fully combined.
Divide the mixture into 4 and shape into burgers using your hands (it's a good idea to push down the middle. Burgers tend to puff up a bit as they cook so this will ensure they look more even when they're ready).
Place on a wire rack over a baking tray and cook for 12-15 minutes until cooked through.
Serve the burgers in a bun topped with cheese and a spoonful of the beer onion jam.
If you want to melt cheese onto your burgers add it a couple of minutes before the end of the cooking time so it can melt as they finish cooking. I used stilton for mine but other strong cheeses work well.
