Hi Hannah, the Marmite is an important ingredient in this recipe. As it’s so thick and sticky it helps bind the meatball ingredients together and it adds a strong savoury flavour too. We would recommend using Marmite or any other similar brand of yeast extract.Supermarkets make their own brands of yeast extract and depending where you live, there are brands such as Vegemite, Bovril and Promite available.

Hey Amber, We work out our recipes on the serving size not by weight. To work out your own weight of a serving you would need to make the finished dish and divide servings, as the weight will vary due to variation of ingredients and water content it’s not something we can do as an exact measure. If you scroll down to the recipe card at the bottom of the page on the website there is a little arrow by servings and you can alter up or down to serve more or less people. Hope that helps!
