Put the chopped tomatoes, orange juice,
lime juice, chopped onion, granulated sugar and chopped green chilies
into a food processor. Process the tomato mixture until very smooth,
scraping down the sides if necessary. Pour the tomato mixture into a jug
and chill well. To serve, pour into small glasses, allowing about 90ml /
6 tbsp per portion. Pour the tequila into separate small glasses. Slip
the tomato juice and tequila alternately.
Plain white tequila is not suitable for
this. Choose one of the amber aged tequilas (Anejos), which are smoother
and more gentle on the palate.
