MODERN KITCHENS · 011 / 100
Roman · Roman Mediterranean · Roman imperial tradition; surviving compilation approximately 4th–5th centuries CE
Evidence: adapted surviving recipe. The historical evidence and modern cooking choices are distinguished below.
Lettuce can soften into a warm bowl while keeping its gentle flavour. Apicius’s lettuce preparation 130 describes a cooked lettuce mixture thickened with eggs. This adaptation chooses a soup consistency, modern romaine and a modest amount of grape juice. The surviving passage supplies the combination; our quantities and texture are practical interpretations.
Use firm lettuce hearts rather than a bag of delicate mixed leaves. The pale centres and ribs contribute enough body to make the soup feel substantial. Wash and dry them, then slice thinly so they cook quickly. A short simmer keeps the flavour mild; prolonged boiling can leave a dull colour and little identifiable lettuce texture.
Beat the eggs in a separate bowl, then introduce hot broth a little at a time before returning them to the pan. This modern tempering step makes curdling less likely. The soup still needs to reach a safe egg temperature, so use gentle heat and a thermometer rather than leaving the eggs barely warmed for the sake of smoothness.
Consult the edition notes when reading the terse source, especially its added culinary wording. This is neither a recovered exact broth nor a medical dish. Serve with plain bread and eat promptly. Fine cooked egg flecks are acceptable; large rubbery lumps usually indicate excessively high heat. If the soup seems too thick, loosen it with hot water after the eggs have cooked.
Warm Lettuce and Egg Soup
Serves 4 · Preparation 15 min · Cooking 20 min
A modern adaptation for home cooking. Times are approximate.
Ingredients
- 350 g romaine lettuce hearts, washed and thinly sliced
- 100 g onion, finely chopped
- 20 ml (4 tsp) olive oil
- 800 ml low-salt vegetable stock
- 40 ml white grape juice
- 3 large eggs
- 1.25 ml (¼ tsp) black pepper
- 1.25 ml (¼ tsp) salt, to taste
Method
- Soften onion in oil over medium-low heat for 5 minutes. Add lettuce and stir 2 minutes.
- Add stock and juice. Simmer gently 8 minutes until lettuce ribs soften.
- Beat eggs in a bowl. Slowly whisk in 200 ml hot soup, then stir this mixture back into the pan over low heat.
- Stir continuously for 3–5 minutes until the soup thickens slightly and reaches 71°C/160°F. Avoid a rolling boil. Add pepper, taste for salt and serve.
Substitutions and adjustments
- Little gem lettuce replaces romaine.
- Water with 5 g honey replaces grape juice as a deliberate modern substitute.
Historical choices: Apicius 130 gives lettuce cooked with liquid and thickened with eggs. Soup consistency and tempering are modern decisions.
Troubleshooting: Egg lumps: whisk gently or briefly blend after the soup reaches 71°C/160°F. Avoid boiling hard.
Storage and reheating: Refrigerate within 2 hours for up to 2 days. Reheat gently, stirring, to 74°C/165°F.
Kitchen note: Cook the egg-thickened soup to 71°C/160°F. Contains egg.
