Ingredients

8 large eggs 

1/3 cup mayonnaise 

1 tablespoon Dijon mustard 

1 teaspoon white-wine vinegar 

1/2 mashed avocado 

3/4 teaspoon anchovy paste 

Trout roe 

Preparation

In a medium saucepan, cover eggs with 1 inch of water. Bring to a boil; remove from heat. Cover and let stand 12 minutes. Drain eggs; run under cold water until cool enough to handle.

Peel and halve eggs lengthwise; remove yolks and transfer to a bowl. Mash with a fork; mix in mayonnaise, mustard, and vinegar. Press through a sieve to make smooth. Stir avocado and anchovy paste into yolk mixture. Press through sieve again.

Using a pastry bag fitted with desired tip (we used plain and star tips), pipe yolk mixture into whites. Garnish with trout roe. Serve immediately, or chill up to 2 hours.
