Raspberry Rhubarb Jam making Hints

The processing time in a water bath is based on your altitude above sea level. Altitudes 1,000-3,000 feet you need to add 5 minutes. 3,001- 6,000 feet you need to add 10 minutes. 6,001- 8,000 feet needs to add 15 minutes. 8,001-10,000 feet need to add 20 minutes to your processing time.

You will notice most jam recipes call for twice as much sugar as my recipe does. Honestly, the reason why I began making my own jam is because I couldn’t stand how sweet store bought jam was. Plus I wanted natural jam, not jam stuffed with preservatives. So I have played with the recipe over the years until I have come up with the perfect level of sweetness. It’s not too tart, yet not too sweet. It allows the flavors of the raspberry and Rhubarb to really sing.

Adding the butter is completely optional. But it will definitely help decrease the amount of foam your jam will produce. You don’t want foam at all in your jam. It messes with the texture and canning process.

Do not double this recipe. If you are processing a lot of jam, you will need to make each batch individually. Ok, so I’m super lazy and I have sometimes doubled this recipe. But let me tell you why you shouldn’t. It only turns out about 50% of the time when you double the batch. Half of my jars turn out with the perfect consistency and the others turn out a little runny. So if you don’t mind runny jam, then go ahead. Otherwise, I’d recommend making each batch individually.

If you have hard water, a cool trick is adding some white vinegar to the water in your water bath. Other wise you will end up with a thick white film on all your jars when you remove them. It’s not harmful. You just have to wash the film off afterwards. But really who wants to do that? Just add a little vinegar to the water bath and poof! No more white film to wash off!

You have a choice which pectin to use in the jam. The Regular Sure Jell Pectin or the No Sugar Needed Sure Jell Pectin. If you happen to use regular Sure Jell with your jam and it turns out more runny than you prefer, then next time you will want to use the no sugar needed Sure Jell pectin. I have used regular Sure Jell and it turns out to a fairly good texture about 90% of the time. But I think next time I will try the no sugar needed pectin and see if I have a better percentage.

One of the most important things you can do when making jam is make sure you have all the ingredients premeasured into bowls and ready to add, before you even begin! It is crucial that you add the ingredients at the right time and not over boil the jam. And crucial that you stir constantly. So when you have the sugar premeasured in a bowl; when the time comes you can simply add it in with one hand while you continue stirring with the other hand.
