Step 1: Prepare Your Ingredients
Start by gathering and prepping all your ingredients. Finely dice the red onion, chop the cilantro, mince the jalapeño (remove seeds for less heat), and dice the tomatoes if using. Juice your limes and set everything aside. This mise en place makes the process smooth and quick.

Step 2: Cut and Prepare the Avocados
Cut each avocado in half lengthwise, cutting around the pit. Twist the halves apart. Carefully strike the pit with your knife blade so it sticks, then twist to remove it. Use a large spoon to scoop the avocado flesh out of the skin into your mixing bowl. Discard the skins and pits.

Step 3: Mash the Avocados
Using a fork or potato masher, mash the avocados to your desired consistency. For authentic guacamole, you want it chunky, not completely smooth – aim for about 75% mashed with some visible chunks remaining. This gives you the perfect texture contrast. Some people like it very chunky, others prefer it creamier – adjust to your personal preference.

Step 4: Add Lime Juice Immediately
Immediately add the fresh lime juice to the mashed avocados and stir to combine. The acid in the lime juice helps prevent browning and adds essential bright flavor. Make sure to coat all the avocado pieces.

Step 5: Add the Aromatics
Add the diced onion, chopped cilantro, minced jalapeño, and diced tomatoes (if using) to the bowl. Sprinkle in the salt and cumin (if using). If you’re adding garlic, include it now as well.

Step 6: Mix Gently
Using a spoon or spatula, gently fold all the ingredients together until evenly combined. Don’t over-mix or you’ll lose those nice avocado chunks. Taste and adjust the seasoning – you may want more salt, lime juice, or heat depending on your preferences.

Step 7: Let It Rest (Optional but Recommended)
If time allows, cover the guacamole and let it rest for 10-15 minutes before serving. This allows the flavors to meld together beautifully. If you’re serving immediately, that’s perfectly fine too!

Step 8: Serve and Enjoy
Transfer to your serving bowl, give it a final taste test, and serve immediately with your favorite tortilla chips or as a topping for tacos, burritos, or nachos. Enjoy the fresh, vibrant flavors!
