However, wait until your baby is at least 6 months old to use a digital ear thermometer. If you use another type of thermometer to take a young child's temperature and you're in doubt about the results, take a rectal temperature. 4 years and older.

Arrowroot is nutritious. It contains more calcium, fiber, folate, and potassium then cornstarch with less sodium and carbs. Now granted, you only use a small amount of either of these ingredients but regardless, more nutrition is still more nutrition. For a side by side comparison check out this site. Arrowroot works better then cornstarch for frozen foods and acidic foods. The most neutral tasting of starch thickeners. When you buy arrowroot it is simply the plant ground up. As far as I know, it is not processed. Arrowroot can be used just like cornstarch. Simply mix a bit of arrowroot with a little bit of cold water and add to whatever you are making. Use the same amount of arrowroot as you would cornstarch. I have also heard that you can use arrowroot to replace flour when you need a gluten free substitute but I have yet to try it out.
When you want 1 cup of liquid to be fairly thick, it takes 1 tablespoon of cornstarch. (A stir-fry sauce might use only 1-2 teaspoons per cup of liquid). It will take about 3 tablespoons of flour to replace 1 tablespoon of cornstarch, and you will need to cook the sauce for much longer to get rid of the raw flavor of the flour. Flour is a very stable thickener, but will not result in the same glossy shine that cornstarch produces. Arrowroot, on the other hand, makes a beautifully shiny sauce and may be substituted in an equal or slightly greater amount, but will need to be cooked a little longer than cornstarch. For other substitutes like potato flakes or granules, tapioca and rice starch, 2 teaspoons will likely thicken about as much as 1 tablespoon of cornstarch.
