I attempted to answer a question via messaging regarding Grand Cairo snuff and submit a fuller answer here which may also interest others.
Which company first manufactured snuff under the name of Grand Cairo remains a mystery, but the name itself was doubtless chosen on a whim and likely has no relation to Egypt beyond the evocative name. The earliest recipe in my possession is by the London House of Taddy & Co and is classed as a Mixed Rappee (Martinique and Coarse Dutch) and flavoured with oil of Rhodium. The latter, according to Charles Lillie, came chiefly from Holland and has an aroma similar to Otto of Roses. Martinique, itself a mixture, contains 100 trays of Fine Dutch and 3 trays of Red Spanish Brick Dust – all liquored with Bay Salt. This doubtless explains why early sources describe Grand Cairo as a Red Rappee, perhaps reminiscent of the red sands of that ancient land.
Grand Cairo, introduced in 1984 by Mark Chaytor at Sharrow was one of eight new snuffs in the Grand Sharrow range and not, as I have said in ‘senior moments’, part of the 1977 Celebratory Range. Sharrow’s version does not contain Red Brick Dust (thank goodness) and is neither red in colour nor a rappee as claimed by Wilsons in earlier descriptions of this snuff. In fact I’m taking some of this refreshing ‘summer snuff’ right now.
