Pectin Recipe Problems

I was hoping someone with more brains than me was able to point me towards where I’m going wrong with my recipe and process? While I’ve had a few batches work, most seem to stay a soft gummy mess and never properly set.

For around 100 pieces, I’m heating and combining:

Glucose Syrup 140g
Sugar 105g

Homogenising the following, then adding to the warm mixture:

Water 97g
Slow Set Pectin 8.5g
Sugar 48g

Cooking to 225F, 80 brix then adding:
Citric Acid 3g
Water 6g
Flavouring 10g

Then flood and scrape.

I’ve tried a few different variants such as hydrating the sugar/pectin mixture first before adding, blending it dry then adding to the mixture dry etc. I read somewhere to try 50/50 citric and malic acid, but that’s not worked either. At this point, I think I can’t see the forest for the trees, so any pointers would be very, very welcome

What exact pectin are you using? Your cook temp seems fine so the issue is likely ph.

It’s HM pectin. I’ve tried going up to 230-235f, but even at that temp the pour time is barely enough and the final texture is still very soft. Any higher and I think the mixture will burn.

try increasing the pectin amount a bit, half a percent of the total weight of the recipe or so

Hm-100 is a little different because it’s pre-standardized, I think it’s also buffered

So moral of this story is buy better pectin.

Yea, everyone uses hm pectin. I’m asking what exact pectin you’re using? What brand, what specific product?

Sorry, gotcha. It’s this one:

That’s probably got sodium hexametaphosphate in it, I haven’t tried that as a buffer, might be complicating things a bit

It looks like you’re using a lot higher amount of glucose proportionally, you could try reducing that in favor of more sucrose as well. I would increase the pectin to start personally

Thanks. The spec sheet I got from the manufacturer only states pectin and dextrose. I’ll try dropping the glucose down and increase the pectin and see how I get on.

Assuming your pectin isn’t already diluted way down by the manufacturer you should already have enough in there to get it to set solid. Again I think your issue is improper ph. I’d also recommend checking out this thread, lots of good info in there.
