When the cafe opens, we'll be rotating sandwiches, testing out fillings and chatting to visitors to see what our customers would most like to see on the menu. Meantime, I am devouring cookbooks, blogs and cafe menus and taste testing any and all sandwich fillings I come across. Really it is the best excuse ever to spend all my time making cakes and going out for coffees - all in the name of research.
This sweet and sour relish is one of my favourite condiments. Its strength is beautiful with blue cheese, the richness cuts through the sharpness of goat cheese and its balsamic sweetness adds depth of flavour to beef or roast vegetable paninis.
Today's lunch will be roast beef sandwiches with caramelised onion relish. A little blue cheese adds depth, a slick of mustard adds bite and a handful of rocket adds a peppery crunch but I love it best served simply with rare beef.
Caramelised Onion Relish
4tbsp olive oil
4 large red onions, finely sliced into half moons
2 cloves garlic, crushed
2 tbsp balsamic vinegar
2 tbsp dark muscovado sugar
Salt and freshly ground black pepper
Heat the olive oil in a heavy bottomed pan. Saute the onions gently for 30-40 minutes until soft and golden. Add the garlic for the last few minutes of cooking and gently stir through the gelatinous oniony mess. Add the balsamic vinegar and sugar and stir well through the onion mixture. Bubble gently for a minute or two to allow the sweet and sour flavours to meld then season to taste. Keep in the fridge and use within a week or bottle as you would chutney or jam (in sterilised jars) where it will keep in the pantry for months.
