How to make a Ballymaloe BBQ Beef Burger

Melt the butter in a pan, add the onions, cover and sweat until soft. Allow to cool and then mix in a bowl with all the other ingredients.
Cook a little of the mixture in a pan and taste to check seasoning. Shape into burgers and toss in seasoned flour, patting off excess.
BBQ at a medium heat, turning as required until fully cooked.
Serve on a toasted bun with cheese shavings, lettuce and don’t forget a dollop of Ballymaloe Country Relish. Simply irresistible!
