I inspect toast to make sure it is brown enough, yet not to dry. I invented a toast test which tests the capability of various toasted breads to support a generous slathering of marmalade. Zero flexation upon loading indicates a passing toast grade. Currently 75% of bread manufacturers fail the toast test. My job is to make recommendations to the bread manufactures as to how to improve the quality of their toasted bread products. I am handsomely paid for my services.
