This recipe is really a play it by ear sort of thing. Begin with the ingredients listed and adjust as your taste buds direct you.
Mash avocados and immediately squeeze the lemon juice to cover the surface to prevent browning. Add in rest of ingredients and stir to blend. At this point, taste dip and make adjustments or let chill and then decide.
Chill in refrigerator or freezer for just a few minutes before serving.
*If planning to serve later in the day, make as listed and hold back some of the mayonnaise to smooth all over top. This will help to keep dip from turning brown. Stir to blend when ready to serve.
