You can make homemade mayonnaise with just a bowl and a whisk. Just be extra patient and prepared to really use your arm muscles! The process is the same as using a blender. Start off with your egg yolks in a bowl and whisk them together. Slowly add a tiny bit of oil at a time and whisk vigorously each time you add a small amount of oil. This process can take several minutes so be extra patient and switch whisking hands if needed. The mayo might not be as thick as the blender will make it, but it's no problem. It can also thicken a little in the refrigerator. Make sure to add the spices, grated garlic and lemon juice last, then whisk to combine.
