I will check the local supermarket. See what's available. I plan to add coffee and coconut after fermentation is completeI add 190 gram in my coconut stout, just toast the flakes until they start to get a bit of colour in them. (have you checked, you should be able to buy them already toasted) 3 days in secondary you could also add about 30 gram of toasted almond flakes with it. this is the amount I use for 21 litres.
