Hot chutney with chilli (Heat rating 5/5) Twice the amount of birds eye chillies as Caramelised Red Onion Chutney, smoked paprika for a gorgeous barbecue flavour and lots more chillies (including Scotch Bonnets), this really is pretty hot. Great with homemade burgers. Storage As with most preserves, once opened these will keep in the fridge for up to 6 weeks, or unopened until the best before date (usually at least 18 months from purchase date).
