Have everything at room temperature.
To the bowl of your food processor or blender, with the steel blade at ready, add:
2 egg yolks
1 whole egg
1 Tbl. French style mustard
grind of black pepper,
pinch of salt
juice of lemon � cup
Turn on food processor, and let run for 10-15 seconds. Then, while still running, dribble in:
2 cups oil.
Use corn or canola oil to keep it light. Drizzle the oil in very slowly while the processor or blender is running. After the oil has been added, shut off the machine and taste the Mayonnaise. You might want to add a bit more lemon juice or salt. This is also the time to add a bit of Tarragon, or a few chives, maybe a tiny touch of a fine curry powder, or anything else that might give it a distinctive flair. Whirl it few more seconds, and scrape into a stainless steel or glass bowl. Enjoy fresh and warm, or chill well before using.
