The issue is what a "spoonful" constitutes. Check the link to the recipe.
This converter table I sometimes use for conversions lists a spoon as 10ml, https://foodconverter.com/ounces-to-cups-spoons-grams-conver...
Why? As it happens, a 1tbsp basin on a utensil, with loose food (e.g. rice, corn, pudding, whatever) heaped atop the basin to its sloughing point, constitutes pretty much exactly a “mouthful” of food (for almost all human skull+jaw sizes age ≥6yo.)
Soup spoons are larger than table spoons, because you can’t heap soup, so you need a larger basin to get a mouthful of soup.
Likewise, 1tsp is the traditional heaped-to-sloughing capacity of a tea spoon—a spoon given with a tea cup+saucer, used for measuring sugar into your tea, and then stirring said tea. These are actually rather uncommon today, as they aren’t sold in flatware sets, but rather must be purchased separately. You may not have ever seen a true tea spoon. If you’ve ever seen a bar spoon, that’s an elongated tea spoon — both have a 1tsp basin.
The answer is that a "spoonful" is not precisely defined. "Tablespoon" and "teaspoon" are defined measurements, but "spoonful" isn't.
The answer from another comment is that the author meant "tablespoon."
> The idea is that when someone says "spoonful", they mean "one unit of the thing as you'd normally apportion that thing, using the spoon you'd normally use when interacting with that thing."
> So, one "spoonful of sugar" (or most spices) is a teaspoonful, because you use tea spoons when interacting with sugar in everyday life; while one "spoonful of honey" (or soup stock, or reserved pasta water, or any other thing that you only tend interact with in the context of cooking) is a tablespoonful. (Or actually, a wooden-mixing-spoon-ful, since that's what cooks had on hand to measure with — but as it turns out, wooden mixing spoons usually had the same level liquid capacity as table-spoons. The heaping measures weren't equivalent between wooden mixing spoons and tablespoons, though, and this has caused much numerical error when modernizing old recipes!)
