On a recent trip to Dublin I was able to visit the facilities of Blakes Ingredients http://www.blakesingredients.com/ where I was treated to a master-class in spices and additives by the staff. I didn't want to impose so I didn't take photos of the installation suffice to say it's the biggest spice-rack I've ever seen. I think I have the spice mix sorted out, now it's a problem to get get the correct casing, apparently the Spanish one I'm using is of a different calibre etc. But Hey Ho! These boys can supply it all plus, they were telling me, they can make up batches of spice mix AND they use the famous Irish rusk. I've brought back a few samples so look out.
A BIG THANK YOU to all at Blakes.
