Receta Swedish bean balls with lingonberry gravy

Here’s a post I never thought I’d write: a post about food packaging (read on, I swear it’s not as boring as it sounds!). Last month I went on a trip to Sweden with Tetra Pak to learn all about a product called Tetra Recart (you might have seen some of my pictures on Instagram!). If you’re not sure what Tetra Recart is, it’s these cartons, which you may have seen in lots of shops in recent years (since 2007, in the UK) – they’re usually filled with foods that you’d expect to see in a tin can, like these black beans (but also tomatoes, soup, fruit, sauces, pet food…):

If I’m honest, when I was first invited to Sweden to learn about Tetra Recart, I thought it might be a bit boring. I can’t say I’ve ever given food packaging much…
