When alcohol is used in cooking, most of the alcohol is evaporated off. But the remaining flavors still give the impression of it. Alcoholic drinks of color have many chemicals in them. These are called congeners. They are partly responsible for the hangovers from whiskey, rums, bourbon, liqueurs, etc. So people who drink alcohol and have PN should only use filtered vodka, unflavored, very lightly because of this.

People vary in response to spices however. I get tingling/burning now from curry. Also on my "to avoid list" for myself, are
paprika, anything from peppers and cayenne, black pepper, excessive nutmeg and pumpkin spice. Any of these will cause burning for me depending on amount and other triggers present which might be additive. Sometimes I get GI reactions too.

However, ice cream itself is loaded with sugar and fat. The fat itself will thicken the blood (increase triglycerides) and in people with circulation issues (elevated bone marrow peptides) this thickened blood will cause the hands and feet to have slow circulation and perhaps elevated PN symptoms.
There was a study on normal people (without health problems) showing very slow blood flow (thickened blood) for several hours after consuming a high fat meal. We have had others here over the years who had symptoms of PN increase after ice cream.
