Tweaked it slightly as no Aperol and as usual subbed a smaller does of Campari (10 ml) but would have actually been better with 15 ml to balance the Orgeat. Upped lime to 20 ml. A simple Tajin is very easy to replicate if again like mine you are missing this; Grate/zest 1 lime onto kitchen paper, transfer to small piece of foil and dry in a very low oven for 20 mins. Then add 1/2 tsp chilli flakes, 1/4 paprika and 1/4 salt. Grind all ingredients together in a pestle and mortar et voila!
