The recipe is posted verbatim here:
350-380g dried spaghetti
50g unsalted butter
1 tsp Marmite
freshly grated parmesan cheese, for serving
Cook the spaghetti in plenty of boiling salted water. While the pasta is cooking, melt the butter in a small saucepan and add the Marmite and 1 tablespoon of the pasta water. Mix thoroughly to dissolve, then pour over the drained spaghetti. Serve with plenty of grated parmesan cheese.So of course I made it the first chance I got but being me and therefore lazy, I omitted the bit where the butter and Marmite is melted together, instead, I bunged it all together after draining the pasta in a hot pan and generously sprinkled cheese all over as well as white pepper. Delish and the ultimate in comfort food.
About the Marmite I used... I had an unopened jar of Guiness Marmite which Umami had kindly given me ages and ages ago. Although it had clearly passed its best before, being unopened, I have no qualms eating it. Its so salty that I would highly doubt something bad had happened to it. Not that I advise other people to do the same but I'm familiar with my tummy (too familiar...) to know what abuse it can take. Now to sit back, relax, eat my Marmite Spag and wait for the cries of EWWWW to pour in...
