I want to buy the thing that was the most expensive and exuberant to manufacture for the lowest price. So yeah, when I want jam, I want jam that is the most strawberries. This isn't complicated.
It is actually complicated in this case, because you want jam. Jam is made with 1 part fruit 1 part sugar. But it is even more complicated now because you want not just any jam, but strawberry jam in particular. This is a low pectin fruit so you have to supply your own. Things also change depending on the type of pectin you go for and I think I better stop here...
And yet some people will pay extra to buy jam with no added sugars but agave syrup. I'd rather pay more to have more fruit and just ... less overall sugars.
