Can you be a little more specific? Are they commercially canned or frozen, or home-packed? Were they just sugared to make the syrup, or were they actually packed in a syrup? What form do you need? Are you talking about converting from pounds to grams? If you give us a little more information, someone here will probably have an answer for you in a jiffy.
Sorry took me so long---I am making a Raspberry Chipotle Sauce.
The recipe I have been using commercially packaged Raspberries in syrup. I don't have the container anymore so I assume some things. Not always able to get that product I tried using Frozen rasperries. Assuming a 5 to 1 ratio, I added water and then 3 cups of sugar. Thicken the final with corn starch. It did not come out sweet enough and in the jar the water seemed to separate from the body of the sauce. Hope that make some since. Alice
Not my area in general but I add no water. I use the cooked down juice of the berries to make my syrup. More flavor that way.
Do you normally use the cornstarch? Or did you because of the consistancy of the product? Just wondering.
