A slice of onion on a burger gives great taste and texture. There\u2019s a time and place for that kind of burger, and another for a melting oozing mess. This Guinness Onion Jam takes caramelised onions to the next level, providing a malty beer base with sweetness from the onions and sugar. <\/p>\n
The jam is good with burgers, especially when paired with a sharp fatty cheese such as a mature cheddar. It\u2019s inspired by recipes for Sticky Onion Marmalade<\/a> from Riverford and David Lebovitz\u2019s Shallot Marmalade<\/a>. <\/p>\n All onion recipes are deceptively simple, with a single main ingredient. The secret is patience, taking the time to really caramelise the onions and ensure they almost dissolve in the beer. You can use any dark beer or stout in place of the Guinness. <\/p>\n 5 medium onions<\/p>\n<\/li>\n Salt \u2013 1tsp<\/p>\n<\/li>\n Pepper \u2013 1tsp<\/p>\n<\/li>\n Guinness Original \u2013 500 ml<\/p>\n<\/li>\n Balsamic Vinegar \u2013 3 tbsp<\/p>\n<\/li>\n Golden Caster Sugar \u2013 50g<\/p>\n<\/li>\n Mustard Seeds \u2013 1 tbsp<\/p>\n<\/li>\n<\/ul><\/div>\n These amounts make just over a single medium 340g jar of the jam, with a little left over for immediate use. <\/p>\n If during the process the pan starts to become dry add a splash of water. You don\u2019t want to colour the onions through them burning or sticking, but through a long low heat. You may also need to add a splash of water when adding the second half of the sugar to ensure it coats the onions evenly and that the jam consistency comes together. <\/p>\n I find a heavy cast iron pan is useful for recipes that need a long and slow cook. Cast iron retains heat well and distributes it evenly. I use a Le Creuset pans for cooking on the hob, they\u2019re expensive but will last for so long that the family can fight over them when I\u2019m gone. <\/p>\n * Disclaimer: I may get commissions for purchases made through links on this page.
