Add 150ml of boiling water and stir (less if you prefer it thicker). Leave to stand for a few minutes. Microwave for 2 minutes. Leave to stand for a few minutes.
Well, I added about 130 m&s of water, left to sit covered for 5mins then nuked for 2.5mins. Result? A bit gloopier that ideal, but actually not bad at all. A tad salty maybe. Overall, quite impressed! Looking forward to trying the others tomorrow.
