Creamy homemade mayonnaise, the simple emulsion of egg yolks and oil, plus a little vinegar or lemon juice and spices. Nothing form a store bought jar compares. It takes a little patience to make, but your tastebuds will be rewarded. If you have never used dry mustard, find it in the spice aisle. If you like it more lemony, add a little lemon juice at the end.
If you get impatient and try to add the oil quickly, your emulsion might “break” or turn to liquid. If that happen, it can be fixed. You will need an extra egg yolk. See notes in the post.
