I bought two boxes of this stuff in Salou last year.
Inside the box are five sachets containing; garlic, bay, saffron, paprika, thyme and pepper (along with other things probably best left unimagined) and you just empty the sachet into the pan when you add the water. It’s a great little cheat, but I only have one sachet left and I won’t be visiting Spain for ages. so if anyone knows where I can buy some in the UK, let me know.
I will post my Paella recipe soon.
