Question: how many grams is one heaped teaspoon?
Answer: A comment by Malcolm Reeves, Food Scientist In fact, I have measured some 400 heaped teaspoons of sugar (rejecting any spoons that could not be taken as true (whatever that means) teaspoons) and found an average of 7.56 g for heaped teaspoons, with a standard deviation of 0.6 g and a little over 4g for level teaspoons.
