Son-in-law eggs, or Kai Palo in Thai, are a delightful dish that transcends the simple fried egg. This iconic Thai street food elevates the humble egg to a crispy, golden-brown masterpiece, boasting a uniquely flavorful exterior and a luxuriously runny yolk.

The name itself hints at a charming backstory, said to be bestowed upon the dish due to its perceived luxuriousness, worthy of a son-in-law.
Beyond the intriguing history, the incredible taste is what truly makes son-in-law eggs irresistible. The contrast between the crisp exterior and the molten yolk, perfectly balanced by the sweet and sour tamarind sauce, creates a symphony of textures and flavors.

FAQs
1. Can I use a different type of sauce instead of tamarind?
Yes! Sweet and sour sauces, or even a simple fish sauce and sugar mixture, can work well. Adjust the sweetness and sourness to your liking.
2. How do I ensure the eggs are perfectly crispy?
Make sure your oil is hot enough before adding the eggs. Don't overcrowd the pan, and ensure the eggs are fully submerged in the oil during the first fry.
3. What if my eggs are overcooked and the yolks are hard?
Reduce the frying time slightly next time. For a perfectly runny yolk, aim for a shorter frying time, especially in the second fry.
