Recipe Ratios: Which recipe uses more chiles?

  • September 9

When using recipes, determining how much of each ingredient is needed is an important task - particularly if you're making an amount different than what the recipe directly instructs! By looking at two different recipes for salsa, and using ratios and unit conversions to make them more easily comparable, we can begin to determine how much of these wonderful garden ingredients we'd need to use for each dish. This material is based upon work supported by the National Science Foundation under Grant... CONTINUE READING

What’s the Scale?

  • September 9

The giant mosaic North Texas Sunrise depicts many native texan flowers, all far larger than life. Using a standard 8.5" x 11" sheet paper as a measuring device, we calculate how much larger the mosaic flowers are than the real thing, determining the scale of the artwork.
