Hi Christine, yes, the pie filling enhancer and the instant clearjel contain the same type of thickener, although the instant clearjel is a bit more potent because it doesn't contain added sugar. I would add about 2 1/2 teaspoons of the instant clearjel to the sugar first, and then mix it in with the raspberries (this helps prevent clumping). You may also find you need to add a bit more sugar when substituting the instant clearjel for the pie filling enhancer. For more information on how to substitute instant clearjel for our pie filling enhancer, check out our Pie Thickener Chart.
