Membrillo is really good with cheese but it needs to be something contrasting, or you need something else in there like an onion jam or even just quick pickled red onions, that would be nice.

If you're tired of pesto, making it with a different green can be quite nice. Arugula pesto is really nice and something of a change.

But wait! My wife is allergic to walnuts (and no other tree nuts, weird huh?)

It's not weird at all. A lot of people with a Type-1 IgE-mediated allergy (anaphylaxis) to tree nuts don't have that response to all of the tree nuts. Similar proteins in the tree nuts group can cause a reaction to the whole group or it can be very specific to a certain tree nut. Also, while peanut and tree nut allergies do tend to cluster, peanut allergies are not really very similar to the tree nut allergies, hence a person who was tested for both peanuts and almonds with a +ve peanut allergy and a -ve almond allergy could happily eat almond butter if it was produced in a facility that does not process peanuts and does not say "may contain" do not try this at home and everyone was very sure to read the labels very carefully.

Distinctly different is cross-reactive proteins, which you find in interesting cases, two of which I will detail:

Environmental allergens can provoke food allergenic symptoms.

1.) In a cohort of Orthodox Jewish patients with dust mite allergies and no prior exposure to shellfish (a prior exposure being necessary for a reaction,) a reaction to shrimp can be noticed after beginning immunotherapy (allergy shots) to dust mites. This likely shows that dust mites and shrimp share enough common proteins to have a cross-reaction. Ramping up the immune exposure to dust mite scat also caused positive skin prick tests in a population fastidious about exposure to shellfish (jab a toothpick in a shrimp then into the skin, compared to +ve histamine reaction and -ve saline reaction.) Shrimp are bugs.

2.) People with allergies to certain trees can develop Oral Allergy Syndrome (or Fruit Reactive Syndrome) in which say, a reaction to cross-reactive birches also causes mild tingling/itch in the face and oro-pharynx upon ingestion of certain fruits (apple, pear, etc.) because of profilin which is a common protein in both. They can eat the fruit cooked with no symptoms, and the proteins are denatured either by heat (by cooking) or by stomach acid so the tingling ends when they swallow. OAS is generally mild but shouldn't be played with as any reaction can be a much worse reaction than the previous one and there is no way to prove what a reaction will be in future.

Latex allergies and banana share a cross-reactive pathway in certain people, although not all; Latex Fruit Syndrome.
