Instructions
Prepare the Egg:
- Place the whole egg (in its shell) in a jar. Cover the egg completely with lime juice. Seal the jar tightly and refrigerate.
Marinate:
- Allow the egg to marinate in the lime juice for 2-3 weeks. The lime juice will soften the shell during this period.
Blend and Serve:
- Once the egg's shell has softened, remove the egg and lime juice from the jar. Place them in a blender and blend until smooth. Add sugar and brandy to taste, blending again to combine everything thoroughly.
Serve:
- Pour the mixture into a glass and serve chilled.

Where it came from
History's hazy on this one, but Leche de Monja feels like it crawled out of a Mexican kitchen, not a fancy bar. It's got the vibe of an old-school folk remedy or a traditional family recipe, passed down through generations who knew a thing or two about making the most of simple ingredients.
This isn't your standard sour or flip. It's in a category of its own, closer to a very patient eggnog, but with a serious citrus kick and a texture that's all its own. The process of dissolving the eggshell with acid sets it apart from any other egg-based drink you'll encounter.
You won't find this on a typical cocktail menu. This is a drink for the curious, for a specific kind of house party, or when you're trying to impress someone with your commitment to a weird project. It's a 'made with love and a lot of waiting' kind of pour.
What it tastes like
Expect a creamy, tangy, and surprisingly smooth experience. The lime breaks down the egg, giving it a unique texture that's rich without being heavy, balanced by the brandy's warmth and the sugar's sweetness. It's got a bright, almost custardy profile with a boozy backbone.
The ABV here depends entirely on how much brandy you pour. If you're going for a decent kick, it'll land somewhere in the 15-20% range, making it stronger than most wines and a good bit more potent than your average beer. Treat it with respect, it sneaks up on you.
The technique
Building this one is a marathon, not a sprint. You're essentially pickling an egg for weeks, then blending the whole thing. A jar for the marinade, a blender for the final mix, and a chilled glass to serve it up. No shakers or strainers needed for the final pour, just patience and a good machine.
The real trick is patience. Don't rush the lime juice bath. Those 2-3 weeks are non-negotiable for getting that shell to soften and the egg to properly break down. It's the whole point of the drink, so let the acid do its work.
Ingredient Spotlight
The bottles that make or break this drink.
Egg
- Use
- Fresh, good quality, large chicken egg.
- Skip
- Old eggs, duck eggs (different shell/membrane).
- Why
- It's the backbone, providing texture and body after its lime transformation. Freshness is key for safety and flavor.
Lime Juice
- Use
- Freshly squeezed, never from a bottle. You'll need a lot.
- Skip
- Bottled lime juice, lemon juice (too different).
- Why
- It's the magic solvent, breaking down the eggshell and infusing the egg, plus providing the essential tang. Bottled stuff won't cut it.
Three Variations
Three real ways bartenders riff on this drink.
Spiced Monja
- A little warmth for the wait.
- Add a cinnamon stick or a few cloves to the jar during the lime marinade for an extra layer of flavor that deepens the final drink.
Citrus Swap
- Orange you glad you tried it.
- While lime is traditional, experimenting with a mix of lime and orange juice can soften the acidity and add a different, sweeter fruit note.
Tequila Monja
- Lean into the spirit.
- Instead of brandy, try a good quality reposado tequila for a more distinctly Mexican character that plays well with the lime and egg.
What if I don't have…
Quick substitutions for when the bottle shop is closed.
Dark rum or a good aged tequila will give a similar warmth.
Agave nectar or honey can work, adjust to taste for sweetness.
A food processor works, or a very patient hand whisk if you've got strong arms and a lot of time.
Any airtight container that fully submerges the egg in lime juice will do the trick.
Frequently Asked Questions
Direct answers to what people search for after Googling this drink.
What is in a Leche de Monja?
It's made with a whole egg, lime juice, sugar, and brandy.
Does the eggshell really dissolve?
Yes, the acidity of the lime juice slowly softens and dissolves the calcium carbonate of the shell over weeks.
Is it safe to drink raw egg?
The lime juice 'cooks' the egg through a process called denaturation, similar to ceviche. However, always use very fresh, high-quality eggs from a trusted source.
How long does Leche de Monja last?
Once blended, it's best consumed within a few days, stored chilled in the refrigerator.
Can I use lemon juice instead of lime?
While possible, lime is traditional and its specific acidity and flavor profile are key to the drink's character. Lemon will give a different, more tart result.
What kind of brandy should I use?
A decent, affordable VS or VSOP brandy works well. Nothing too fancy, nothing too cheap. You want something smooth but with character.
Why is it called 'Nun's Milk'?
The name likely refers to its pale, creamy appearance and perhaps its perceived restorative qualities, though the exact origin is debated and no one's quite sure who put it together.
Can I scale the recipe?
Absolutely. Just ensure the egg is fully submerged in lime juice during the marinating phase, regardless of how many eggs you're processing.
