Yemas de Santa Teresa (Egg Yolk Sweets)
Why this recipe works
- Short ingredient list: Sugar, yolks, water, and lemon create a distinctive sweet with very little added complexity.
- Citrus balance: Lemon zest and juice cut through the richness of the yolks and keep the sweetness from feeling flat.
- Slow thickening: Gentle cooking and constant stirring turn the yolk syrup into a smooth, dense paste without letting it boil.

Common mistakes
- Adding the syrup too quickly: Pour the hot syrup into the yolks in a thin stream while whisking constantly; adding it all at once can scramble the yolks.
- Cooking over too much heat: Keep the pan on low heat once the yolks are added. The mixture should thicken gradually rather than bubble.
- Stopping before the paste is thick: The mixture needs to pull away from the sides of the pan before cooling, otherwise it will be too soft to roll cleanly.
Timing notes
- Chill before shaping: The paste is much easier to roll once firm. If it still feels sticky, give it a little longer in the fridge.
- Serve at room temperature: Let the sweets stand briefly after refrigeration so the texture softens and the flavour is fuller.
Ingredient notes
- Use good egg yolks: Because yolks are the main flavour, fresh, good-quality eggs make a noticeable difference.
- Choose unwaxed citrus if possible: The zest goes directly into the syrup, so an unwaxed lemon is the best choice when available.
- Consider pasteurised yolks: For anyone more vulnerable to foodborne illness, pasteurised egg yolks are the safer option when available.
Authenticity notes
- Ávila speciality: Yemas de Santa Teresa are closely associated with Ávila in Spain and belong to the country’s tradition of yolk-rich convent-style sweets.
- Simple presentation: The recognisable finish is plain and understated: small rounded sweets coated in fine sugar rather than iced or decorated.

Ingredients
Instructions
- Put 150 g of the caster sugar and the water in a small saucepan. Finely zest the lemon into the pan, then add 1 tbsp lemon juice. Heat gently, stirring just until the sugar dissolves.
- Bring the syrup to a gentle simmer and cook for 3 to 5 minutes, until it looks slightly thickened and glossy. Take the pan off the heat and let it stand for 2 minutes so it is hot but not fiercely bubbling.
- Put the egg yolks in a mixing bowl and whisk briefly to loosen. Slowly pour in the hot syrup in a thin stream, whisking constantly so the yolks do not scramble. Strain the mixture back into the saucepan to remove any bits of cooked yolk and the zest.
- Cook over low heat, stirring constantly with a whisk or wooden spoon, until the mixture becomes very thick and starts to pull away from the sides of the pan. This usually takes 8 to 12 minutes; keep the heat low so it does not boil.
- Scrape the paste onto a plate and spread it out slightly to cool faster. Chill until firm enough to handle, about 20 minutes.
- Put the remaining 50 g caster sugar on a plate. With clean, slightly damp hands, roll the paste into small balls, then roll each one in the sugar to coat. Serve at room temperature.
Recipe notes
Tips
- Keep the heat low when cooking the yolk mixture; it should thicken slowly without boiling, which helps keep the texture smooth and fudgy.
- If the paste feels sticky when shaping, chill it for 10 minutes more, or lightly dampen your hands before rolling.
- Food safety: this recipe contains egg yolks that are cooked but not to a set custard; if serving to pregnant people, young children, older adults, or anyone immunocompromised, use pasteurised egg yolks if available.
Substitutions
- Replace the lemon with lime for a slightly sharper citrus note.
- Replace 30 g of the caster sugar with light brown sugar for a faint caramel flavour and deeper colour.
Storage
- Refrigerate up to 5 days
- Store in an airtight container in the fridge, with a little extra caster sugar to prevent sticking. Bring to room temperature for 15 to 20 minutes before serving; if the coating looks damp, roll again in caster sugar.
