Peanut-Lime Noodles with Prawns

We’re trying to eat a little more healthily this summer, after a few months of indulgence. As such, there are more salads and stir-fries in my planner at the moment. Not that these are all inherently healthy, but I do find portion control a lot easier in a stir-fry – and portion control has historically been my weakness.

Following on from my recent post about my Universal Stir-Fry Sauce here’s another quick stove-top recipe in a similar vein. Peanut-Lime Noodles with Prawns. Though admittedly the end result here is quite a bit richer than the soy-based sauce from the previous recipe.

The base of the noodle sauce here is peanut butter. This brings a lovely flavour, but also gives a thick, creamy texture that helps the sauce cling to the noodles and delivers flavour to every mouthful. I think that your choice of peanut butter here is important. I use one that’s 100% peanut and contains nothing else I’d like to avoid – like sugar, salt or preservatives – where they’re not needed.

Yes, you could argue whether that matters when I add soy sauce and sugar to the sauce later on. But I would argue that it’s my choice of how much to add. If you don’t want them then by all means use an alternative or just miss them out altogether. Even though things are improving there is still a lot of hidden sugar and salt in processed foods and I like to avoid them where I can.

The other flavourings in the sauce are there to balance the richness of the peanut butter. The primary flavour being lime, which brings a lovely freshness and acidity. I also think a bit of lemongrass and some coriander can really help lighten the sauce and make it ideal for a summery supper.

The peanut butter in this sauce gives it a thick, sticky texture which ensures it clings to the noodles in this quick stir fry, whilst the lime adds a fresh hit and balances out the richness.
