Ah! Troach. A black-country delicay. A boiled sweet with a dark brown colour, originally made by Teddy Grays (Dudley) and Sela (West Brom). I am told Teddy Grays still manufacture. Sela sold out to Paynes in Newport S. Wales and that passed to Brays also of "Nuput".

Most people cite aniseed as the flavour but it is a modified flavour thereof. Originally, before EC elf and siftie got on the case, the flavour was Paregoric though that had aniseed to hide the essential ingredient. Tincture of opium would be close though paregoric is about 1/20th the strength. "Army & Navy" had the same flavouring though much stronger - possibly less aniseed. Victory V lozenges had the same ingredient and any aniseed was barely discernible. Kaolin & Morphine medicine, unsurprisingly had the same kind of taste as Victory V.

I still buy Troach whenever I can find it, the big advantage is that girlfriends don't particularly like them. All the more for me!
