Rompope is documented as a 17th-century invention of the Convento de Santa Clara in Puebla, where the Clarissan nuns adapted Spanish-Iberian egg-yolk drinks (ponche de huevo) by adding indigenous vanilla and the sugar-cane aguardiente then circulating through colonial Mexico. The yolk-heavy Pueblan version diverged from European eggnog by being cooked (not raw) and bottled at higher alcohol — a stable, gift-able convent product. Santa Clara's recipe spread through Pueblan home kitchens, and «rompope de Santa Clara» remains the regional benchmark.
Convento de Santa Clara, Puebla, 17th century — Clarissan nuns adapted Spanish ponche de huevo by adding native vanilla and colonial sugar-cane aguardiente. Cooked, not raw, which is the divergence from European eggnog. The 4-8% final ABV preserves the bottled drink for weeks at fridge temperature.
Rompope pours pale yellow and thick — between heavy cream and a thin custard sauce. The first sip is rich on yolk and milk, then sugar, then a slow heat from rum on the back of the throat. Cinnamon and vanilla sit underneath. Cold from the fridge, it coats the mouth and lingers; warmer it gets winey and loose. Drunk after dinner in a small glass, sometimes poured over ice cream or a slice of cake, sometimes sipped solo with a polvorón.
Rompope is a thin custard stabilised by alcohol. The cooking step pasteurises the yolks and sets a gentle starch-free thickening from the yolk lecithin and proteins — too hot and the proteins curdle, too cool and the drink stays watery. The 4-8% final ABV does double duty: flavour, and microbial preservation that lets bottled rompope hold for weeks at fridge temperature, unlike fresh custard sauces which sour in days. Adding alcohol after cooling preserves both alcohol potency (high heat would evaporate it) and the volatile vanilla aromatics.
Variations
Rompope de Santa Clara is the Pueblan benchmark; Oaxacan version uses local mezcal as the spirit; Yucatecan riff adds local Xtabentún anise liqueur; commercial Coronado bottles are widely sold but run thinner than convent-style.

How it's made
6 steps · 35 min active + 25 min waiting
- 118 min
In a heavy pot combine 1L whole milk, 200g sugar, 1 stick canela (8cm), and a split vanilla pod (or 1.5 tsp extract added at the end). Bring to a low boil over medium heat, then drop to a steady simmer 15 minutes — the milk reduces slightly and takes on the spice.
Watch outStir occasionally; milk pots scorch fast on the bottom even at low heat.
- 28 min
Strain the infused milk through a fine sieve into a clean bowl, discarding the canela and pod. Cool to about 60°C — hot enough to cook eggs slowly, not so hot it scrambles them on contact.
- 34 min
Whisk 8 egg yolks in a separate bowl until pale. Temper: ladle in 200ml of the warm milk while whisking continuously, then a second 200ml. The yolks are now warm and dilute enough to handle the rest.
Watch outIf yolks scramble at this step, dump and start over — strained custard with bits is not rompope, it's bad sauce.
- 410 min
Pour the tempered yolk mix back into the milk pot. Cook over very low heat, stirring constantly with a wooden spoon in figure-eights, for 8-10 minutes until the mixture thickens enough to coat the back of the spoon — runs but leaves a clean track when you draw a finger through.
Watch outMaximum 82°C — eggs scramble at 85°C+. If unsure, use a thermometer; this is the single point where rompope can fail.
- 525 min
Pull off heat. Stir in 1.5 tsp vanilla (if using extract) and a pinch of salt. Cool to room temperature, stirring occasionally to prevent skin. Once at room temp, stir in 200-250ml dark rum or aguardiente de caña — alcohol added hot would flash off.
- 65 min
Strain once more into bottles, cap, refrigerate at least 4 hours — chilling tightens the texture and rounds the alcohol. Serve in small glasses, neat, ice-cold, often with a dusting of cinnamon. Keeps refrigerated 2-3 weeks because of the alcohol.
