Marmite chilli sauce anyone? If you love Marmite and twiglets then Firemite is the sauce for you. Made with Naga chilli and loads of yeast extract we have incorporated that amazing beefy flavour into this spicy sauce hence the name! Amazing on cheese on toast also a splash to any mince dish, spaghetti bolognese, shepherds pie and chilli etc. One of our original sauces that has stood the test of time and is always asked for at shows and events.
