Ingredients

  • 5 large egg yolks
  • 3/4 cup sugar
  • 2 tablespoons cornstarch
  • 1/4 teaspoon vanilla
  • 2 1/2 cups milk

Instructions

  1. Combine egg yolks and sugar in a medium saucepan.
  2. Gradually add cornstarch and vanilla, whisking constantly.
  3. Add hot milk, whisking continuously to incorporate.
  4. Cook over very low heat or in a double boiler, stirring constantly, until thickened, about 5 minutes.
  5. Allow to cool before serving.

Tips & Substitutions

For a richer custard, consider adding a splash of rum or using brown sugar instead of white. If you need a gluten-free option, cornstarch is a great thickening substitute. Whisk constantly when incorporating the milk to prevent lumps. Make sure your milk is hot but not boiling to achieve the perfect consistency without curdling the eggs.

Serving Suggestions

Serve the rum custard cake chilled or at room temperature. It pairs beautifully with fresh fruits like berries or a drizzle of caramel sauce. For a delightful contrast, consider serving it alongside Creamless Asparagus Soup or a light salad, making it a perfect dessert for a spring gathering.

Storage & Reheating

Store any leftover custard cake in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm it in the microwave on low power or over a double boiler, stirring occasionally to maintain a smooth texture. Avoid reheating too quickly, as this can cause the custard to separate.

Frequently Asked Questions

Can I use whole eggs instead of just egg yolks?

While you can use whole eggs, the texture of the custard will be different. Using just egg yolks creates a creamier and richer custard, so for the best results, stick to the recipe's suggestion of using only yolks.

What can I substitute for milk in this recipe?

You can substitute whole milk with almond milk or coconut milk for a dairy-free version. Just ensure the alternative milk is unsweetened so it doesn't alter the flavor of the custard. Additionally, using a thicker plant-based milk can help achieve a similar consistency.

How can I tell when the custard is thick enough?

The custard is ready when it coats the back of a spoon and holds a line when you run your finger through it. It should take about 5 minutes over low heat, but keep stirring consistently to prevent it from sticking or burning.
