Finnish Egg Sauce

Finnish Egg Sauce is my family's version of this classic Nordic sauce. Made with hard-boiled eggs, fresh dill, chives, and a splash of lemon juice, it's the perfect accompaniment to boiled or breaded fish, smoked fish, new potatoes, and seasonal vegetables.

Notes

This is my family's version of Finnish egg sauce. We like to add both fresh dill and chives, along with a little lemon juice to brighten the flavor. There are many variations of egg sauce across Finland, and this is the one I grew up enjoying.
The stock gives the sauce extra flavor. I often use vegetable stock.
Fresh herbs provide the best flavor, but frozen dill and chives also work well.
Leftovers can be gently reheated over low heat. Add a splash of milk if needed to loosen the sauce.
The sauce is very delicious with boiled vegetables too.
