Recently I've learned about salt potatoes, which is a regional dish from Syracuse, NY. Basically, you put about 1 cup of salt to 6 cups of water and boil unpeeled potatoes in that water. I've also watched this video before trying to cook - https://www.youtube.com/watch?v=IochM2MoIDA.

What I got as a result was very tasty, however, the thing is that, apart from lightly salty peels, my salt potatoes tasted exactly like regular ones.

In Wikipedia it is said that:

The resulting potatoes are creamy, as the starch in the potatoes cooks more completely due to the higher boiling temperature of the extra-salty water.

My question would be--what sets apart (in terms of taste) salty Syracuse potatoes from regular ones, and how can I understand that I've cooked them properly? Maybe I've just used too little salt, maybe the salt shouldn't be regular kitchen salt. Maybe I should boil the potatoes longer (I was afraid that peel would burst and the potatoes would get over-salted).

In other words--again, apart from salty peeling--how can an experienced blindfolded gourmet recognize salty Syracuse potatoes?

    Adding salt increases the boiling point of water only a little. For a significant increase in cooking temperature, you could use a pressure cooker. I prefer potatoes cooked that way, but other people don't notice a difference between normal and pressure cooking.

    When I had them (from a co-worker who grew up in Syracuse and brought some back from a trip back home), they were fingerling potatoes, not simply new potatoes. want to say the salt came with the potatoes (a bag of salt in the bag of fingerling potatoes), and I didn't examine it closely before cooking.

I've made these before, and in fact found them to be as you describe; well-salted new potatoes, but not somehow substantially more creamy than standard boiled baby new potatoes. You don't say if you used actual new (young) potatoes, but I did, and did not get different results from yours.

Should it have been different? Well, first, how much "higher" would that boiling point be?

Boiling temperature of water increases by 0.5 C for every 116 grams of dissolved salt per kilogram of water, so for the Chef John recipe, we are looking at an increase of ( 273g / 116g ) * 0.5 / 1.18l, or an increase of just about 1C. This seems unlikely to make a substantial difference in starch texture -- starch conversion temperature ranges are much broader than that.

So, what's the appeal of Syracuse potatoes other than just being salted?

I think I can answer this using quotes from Good Eats:

The consensus among the true believers is that “new” is also an important part of the perfect salt potato equation. New potatoes are simply immature potatoes of any variety, usually harvested in the spring and early summer. Key characteristics of new potatoes include their tender, parchment-like skin, which never needs to be peeled, and their moist creamy texture. Note that new potatoes are not the same as small potatoes.

As the potatoes cook, the supersaturated salted water forms a subtle crust on outside and somehow seals the potatoes so they never taste water-logged like ordinary boiled potatoes often do. They have a unique texture closer to fluffy baked potatoes, only creamier.

I have to say that "somehow seals the potatoes" is a disappointingly unscientific statement from Alton Brown, particularly since we know already from brining that heavy salting affects how various cooked foods absorb and release water. And that is different here, because normal cooking time for small new potatoes is more like 10-15 minutes and the salt boil allows the potatoes to boil for more than 50% longer without becoming waterlogged and mushy.

But here's another important part:

Back in the 1800s, blue-collar Irish miners in The Salt City headed off to work each day with a small bag of substandard potatoes.

Note the "substandard" potatoes, which might include young potatoes that are too green or too hard. Likely for those the extra 8 minutes of cooking time makes a much larger difference that it does for the near-perfect baby potatoes I bought.

So, my conclusion: the primary reason to do Syracuse salt potatoes is because they come pre-salted out of the pan. The secondary reason is because the longer cooking time benefits the texture of the potatoes in subtle ways, but this difference is very subtle indeed if you start the recipe with high-quality potatoes that would have been creamy anyway.

    I'd suspect that the variety of potato will also affect the outcome. A highly starchy potato used for fries will be different to that used for boiling etc.

  • Yes, the classic variety is young white potatoes, such as an allegany

  • Good find on the exact number of boiling temperature per increasing salt concentration. I always knew it is too little to matter for "standard" salting, as in adding more salt to the soup, but I couldn't have said if this 16% salt concentration will have a noticeable effect or not.

  • Thanks. I knew there had to be math for this somewhere. Incidentally, the maximum you can raise the temp of boiling water with salt is 1.5C. So any time we get another "raising the boiling temp" question, we can refer it back here.

Adding that much salt will raise the boiling point, which may have an effect on the creaminess of the potatoes, however I've seen no actual evidence of that.

If you wanted to compare you'd have to do an experiment where you used identical potatoes, the same amount of salt and water in the same pots and controlled for temperature. In one pot you'd let it get as hot as it can, in the other you'd turn down the heat once it reaches 100°C (212°F). Cook them until they reach the same fork doneness level, then drain and serve blind. If the high temperature ones have a creamier texture you have an answer.

    You can’t do much fork testing with salt potatoes, it is important to not have holes in the skin.

    Alternative experiment that eliminates the salt variable but adds others. 2 vessels. vessel 1) Prepare as described in the original question. vessel 2) Boil potatoes for specified time with no salt and only 1 cup water in your favorite pressure cooker. Mash or rice or whatever you do to break up the potatoes separately by vessel. Add same ingredients (dairy, S&P) to both vessels. Compare "creaminess." Speculative opinion: I would be pretty surprised if there's enough of a difference in the final product to make anyone change their go-to way of making mashed 'taters Jan 26, 2020 at 23:19

From the linked video - I've never seen anyone boil potatoes without the pan lid on. I don't know how much that actually would raise the temperature, but it definitely 'increases the boil' somehow.
You can see this best if you're simmering at the lowest temp with a glass-lidded pan. Take the lid off & the bubbling almost stops; put it back & it increases again.

The recipe looks pretty much identical to Canarian Potatoes, except they get a little extra dry heat after pouring the water off.
When I make those, I just give them 20 mins or so at the boil, which is longer than I would for mash. As noted, you don't want to be poking holes in them too much, but they really shouldn't fall apart if you give them just a few minutes longer.
It could be the potato type itself - maybe experiment with different varieties from waxy to floury - but for my Canarians I just use whatever I can get in a small size; I don't actually specifically look for 'new potatoes' [waxy] as it says in the Wikipedia link. I've never thought the real ones from the Canaries used new pots either & I've eaten them a lot.

It's usually pointless trying to use 'named potatoes' between UK & US recipes, as we simply don't seem to have the same types in common at all, but I'd use Maris Pipers rather than Charlottes, for example, though usually there's a complete lack of identification on the packs in the UK, they're just labelled "small potatoes".
