I have always used Bruce's canned Yams for My Sweet Potato Casserole. Unfortunately, this year with the pandemic, I cannot find any available. I still want to make the casserole and want it to taste the same. I know to boil the yams, but what else do I need to do in order to get that sweet taste?

  • A metric ton of sugar and probably some vanilla. We don't really do recipe recommendations here, but simply googling for "sweet potato casserole with fresh yams" yields lots of recipes. – user141592 Nov 20 '20 at 19:57
  • Corn syrup would be a quick substitute. Water it down until it's the same consistency as the syrup that comes with the canned sweet potatoes, and use as much of the watered-down syrup as you would normally use from the can. – csk Nov 21 '20 at 06:05

If you want to devote the time to get the maximum sweetness, you can take advantage of natural enzymes to accomplish your goal. If you can hold your yams between 135 and 170°F (57 and 77°C) for a couple of hours, you can dramatically increase the sweetness. They will still be hard at this point, so will need roasting to soften. A sous vide device will be the best way to do this, but you can do a decent job of improving sweetness by roasting, wrapped in foil, in a 300 F (149 C) oven for about 2 hours. The science and process is explained in detail here.

From Bruce's Yam's:

Bruce’s canned yams (sweet potatoes) use only the tender most part of the sweet potato called the sweetheart. As the number one selling canned sweet potato in the U. S. it has been referred to as America’s favorite – sweetheart. Certified by the American Heart Association.

From McCALL FARMS:

Ingredients: Sweet Potatoes, Water, Corn Syrup, Sugar.

So basically, only use the sweetheart (center) of the sweet potato, and add a good amount of sugar and/or syrup.
