Sadly, I turned out not to have any dry sherry ! The only sherry in the fridge was a Pedro Ximenez which is like concentrated sultanas and would not be at all right. :-(
Also did not have the Tabasco, but substituted with a spoonful of the pickling liquor from a jar of red jalapeno peppers, which gave a nice heat plus a little vinegary depth. Usually I would splash in some Lea&Perrins but this time I didn't.
Temperature wise: tetrapak of Tomato Juice in fridge bottom compartment, ditto bottle of Stoli vodka. Put a dozen small ice cubes in cocktail shaker, add 6 oz vodka, the jalapeno liquor, and about a third of a pack of TJ, swoosh gently (don't shake!), tip into 3 glasses, garnish with a lime wedge and with bit of celery from the centre of the head (*), twist of black pepper, serve outside on a hot afternoon. Didn't have a thermometer on it but it beaded the glasses with a bit of condensation.
Seemed pretty fine to us. On reflection, could have done with a pinch of salt. And:
(*) the stick of celery seems a bit of a nuisance and I can't say improved it for me.
