Combine the egg yolks, garlic, lemon juice, mustard powder, and salt in a food processor for about 30 seconds.
With the food processor running, slowly add the olive oil. It will take 1-2 minutes to achieve the perfect consistency, so take time and add the olive oil little by little.
Add the dill and process for another 30 seconds.
Notes
Expert Tips:
Ensure that all ingredients are at room temperature before starting. Cold ingredients can make it more challenging to achieve a proper emulsion.
When combining the oil with the other ingredients, add it gradually and in a slow, steady stream while the food processor is running; the gradual addition helps to achieve a stable emulsion (the two liquids combine and don't separate).
