Servings 2 people



  • 1 ripe avocado
  • 3 slices red onion (chopped or diced)
  • 1 length jalapeño, seeds and ribs removed (see notes)
  • juice from ¼ or ½ lemon (depending on the size of your avocado)
  • ¼ teaspoon salt
  • teaspoon freshly cracked black pepper
  • pinch cayenne (optional)
  • ½ teaspoon fresh cilantro (chopped, optional)
  • 1 clove garlic (minced, optional)
  • 4 cherry tomatoes (chopped, optional)


  • Cut open your avocado to make sure it’s good. If it is, great! Set it aside. If it’s not, I’m sorry, you’ll need to use a different avocado.
  • Combine chopped red onion, lemon juice, and pinch of salt in a bowl to quick-pickle. Stir and let it sit while you prep the rest of the ingredients.
  • Mince the jalapeño and any other optional additions (cilantro, garlic, tomatoes, etc). Set aside on your cutting board.
  • Use a fork to scoop the avocado out of the skin and into the bowl with the lemon and onions. Use the fork tines to mash the avocado into large chunks.
  • Add the jalapeño, another few pinches of salt (~¼ tsp), the ground black pepper, and any of the optional additions, to the avocado. Continue mashing with the fork or a muddler until you reach your desired consistency.
  • Adjust to taste — add more lemon, salt, pepper, etc if you think it needs it. Serve!


  • To slice a length of jalapeño, remove the top with the stem and the bottom tip of the pepper. Stand the pepper upright, with the stem-end on your cutting board. Look for where the ribs of the pepper are attached, then slice downward removing a length of the pepper from between two of the ribs. A pepper usually has 3-4 lengths, so you’re looking for a section of pepper with no ribs or seeds — just the wall of the pepper, removed cleanly.
  • Avocado browns quickly, so if you do plan on storing this for later press a sheet of saran wrap smoothly against the surface of the guacamole to keep air from reaching it. Then stretch another sheet of saran wrap or a container lid over the top as well. It won’t stay good for days, but you might be able to eek another 24 hours out of it.
  • If you don’t have a jalapeño pepper, a poblano, Serrano, or Fresno pepper will work fine. Since those peppers differ from the jalapeño in size, aim for anywhere from 1-3 tablespoon chopped/minced pepper, depending on how hot you want it or how big your pepper pieces are.
