Foi Thong (Golden Egg Threads)
One serving has 284 kcal and 6 g protein, and at least a fifth of a woman's daily need of choline (77%), selenium (41%), cobalamin (33%), pantothenic acid (24%), phosphorus (22%) and vitamin A (22%). Ready in 20 minutes.

- Preparation: 5 min
- Cooking: 15 min
- Makes: 1 serving (110 g)
- Difficulty: Hard
- Diets: Vegetarian, Gluten-free, Dairy-free
- Contains: egg
Ingredients
- 40 g Egg yolks, raw
- 40 g Sugar
- 30 g Water
Method
- Bring the sugar and water to a simmer in a wide, shallow pan and cook for 2-3 minutes to make a light syrup; keep it at a gentle simmer.
- Strain the egg yolks through a fine sieve to make them perfectly smooth and remove the stringy membranes.
- Spoon the yolks into a small piping bag or a paper cone with a very fine tip.
- Drizzle the yolks over the simmering syrup in thin, continuous circular threads, working quickly so they don't pool.
- Cook each batch of threads for about 30 seconds, just until set but still tender, then lift out with a fork or chopsticks onto a plate.
- Gently gather the threads into a loose coil while still warm, and repeat with the remaining yolk until all the syrup is used.
- Serve at room temperature; the threads keep their delicate sweetness on their own or as a garnish for other Thai desserts.
