How to flip your fridge
If your family are always arguing about what should go in the fridge and what shouldn’t, this ultimate guide will settle it once and for all

1. Care for your condiments
Ketchup

Mustard loses its heat at room temperature, so if you value that delectable punch, stick it in the fridge. Ketchup and brown sauce is fine kept in the cupboard, as long as you’re planning to use it within a couple of months, and who wants chilled sauce on their sausages? Mayonnaise is another matter though, as the lower sugar content and added egg make it vulnerable to bacteria, so keep it in the fridge.

Tahini, the hummus lover’s staple, can stay in a cupboard if you are getting through a jar in less than a month, but any longer and it may go rancid, so keep it in the fridge: it’ll go hard, so you may need to warm the jar in a bowl of hot water before spooning it out.

Some of the smart jars of harissa, pesto and tapenade do need to stay in the fridge once the jars have been opened, breaking the vacuum seal. After you’ve used a bit, flatten the surface with the back of a teaspoon, then top with a little oil to form an airtight seal and they’ll last longer
