Unfortunately the charcoal supplier I use has run out of restaurant grade charcoal (apparently the double bank holiday weekend has "sucked the charcoal supplies out of the country")...somebody took the last 5 bags recently even though they were split ...I suspect it was someone on this forum Anyhow, the chap suggested sawdust charcoal which a local Indian restaurant in Northampton (Memsahib) swear by and gave me a box to try. He assured me that no binding agents or other chemicals are used in making this simply high pressure to compress these, anyone had experience of using this stuff (Pringle can to give some idea of the size of these)?
