Making a dip that's not too sour or spicy can be a challenge. Make the perfect recipe for dipping chips into, and post it here!

2.build

collect

  • Bowl, blender or fork for hand-smashing
  • Can of beans (you choose variety)
  • Tomatoes, onion, spices, spicy peppers, or anything else you think might taste good

activity

  1. Pick a question you'd like to answer about bean dips, that involves making several different variations.  For example, which beans make the smoothest dip?  Or, how much salt should be used to flavor a black bean dip?
  2. Design an experiment plan to answer your question.  This just means, write out each of the variation of the recipe you want to try (can be as simple as 1. NO SALT, 2. SALT, 3. EXTRA SALT)
  3. Measure out a certain amount of each ingredient, and put it into the blender or food processor (ask your parent for help), or simply put it in a bowl to be smashed with a fork.
  4. Blend the ingredients together into dip, and taste it!  You should be able to answer your initial question by tasting the different variations.
  5. You may want to repeat the process, changing the ingredients till you get a dip that tastes just perfect to you.

Tomatoes are really acidic fruit. Some people like the taste of fresh tomatoes, but some people find the sourness caused by the acidity too overpowering. Some vegetable, like onions, celery or carrots, can absorb the acidity of tomatoes and make them taste less sour.
