Fill up a long
glass — or maybe a short one, or it could be a mug if necessary — with ice (melted or frozen, either will do), pour in the tequila, the orange
juice (or it could be apple, tropical or grapefruit), and add a dash, or
loads,
of grenadine syrup, then garnish with a slice
of orange.
A sample breakfast: a bowl
of Rice Krispies, a
glass of orange
juice, a piece
of white toast with commercial peanut butter = massive sugar
load for the pancreas to mop up.
