This is the most wonderful garlic aioli, and all you need is a platter of crudites (raw vegetables) and bread and you have a fabulous starter for a crowd.
It is highly recommended to purchase a stick blender like this one;

Then all you need is;
3 large whole cloves of garlic, peeled and halved
4 eggs, at room temp
2 to 2 1/2 cups good olive oil
1 to 2 tsp fresh lemon juice
salt

Get a tall glass jar and put in the garlic halves and the 4 whole eggs.
Now, add your stick blender and sit it on the bottom of the jar, over the ingredients and turn on.

Very gradually, add the olive oil in a steady stream, keeping the stick blender on all the time.

You will end up with a gorgeous thick garlic mayonnaise. Now put in the lemon juice a tsp sat a time, sprinkle in a little salt, blend with the stick blender, and taste until it’s the perfect flavor for you!
