This is a drink that in the UK is associated with lemon, salt and Neurofen (of any variety!!) For anyone interested in a recommendation, I travel frequently to California and following a conversation with a Mexican friend, she suggested I try some high-end Tequila rather than the BBQ lighter stuff we get in the UK. There is a superb Mexican restaurant in Paso Robles, Fish Gaucho, with a large selection of Tequila and I tried most of the recommended types over a couple of evenings. The Casa Nobles Anejo is simply superb, very much like a smooth cognac with a tequila after-taste.
I may just be enjoying a small glass to celebrate my new (watch) arrival.
