RecipeFix guide
Solving one restriction at a time can create a new problem. Multi-diet cooking works better when every replacement is checked against the full set of constraints before the method is rewritten.
Imagine converting a creamy pasta to dairy-free and nut-free. Cashew cream is a common dairy replacement, but it immediately breaks the nut-free requirement. Almond flour can solve a wheat-flour problem and create the same conflict. Honey can be acceptable for some vegetarian eaters and fail a vegan request.
The right approach is not 'make it dairy-free, then make that result nut-free.' It is to choose every replacement against the intersection of all active constraints from the start.
Some restrictions are mainly about whether an ingredient is present: gluten-free, dairy-free, vegan, vegetarian, and nut-free are examples. Other goals depend on quantity and nutrition, such as high-protein, low-sodium, low-fat, low-carb, or keto. A recipe can contain only low-sodium ingredients and still end up high in sodium if the quantities are large.
RecipeFix is explicit about that difference. Its methodology page lists which constraints receive deterministic post-adaptation scans and which cannot honestly be verified by a word list alone.
A multi-diet recipe often fails in the ingredients that look incidental: broth, sauces, spice blends, tortillas, breadcrumbs, chocolate, and condiments. Soy sauce can introduce wheat. A stock may contain dairy or gluten. A packaged replacement can have a different allergen profile from the category it belongs to.
A good adaptation calls out label checks where the answer depends on brand rather than pretending a generic ingredient name is a guarantee.
Offering a second substitution is useful only if the alternative is also compatible with the full request. A dairy-free primary swap followed by a nut-based alternative is not helpful when nut-free is active. The same full-constraint check should apply to optional toppings, garnish, and ingredients mentioned only inside the method.
RecipeFix lets you select multiple dietary profiles together. It chooses substitutions under the combined request, then rewrites dependent cooking steps and scans supported presence-rule diets after generation. That is more coherent than repeatedly converting an already converted recipe and accumulating contradictory changes.
Yes. Evaluate every ingredient against both constraints, choose replacements that satisfy both, and then update the method for any technique changes caused by those replacements.
Avoid common nut-based vegan substitutes such as cashew cream and almond flour. Choose plant-based replacements whose ingredient lists also meet the nut-free requirement, and check packaged products by brand.
Yes. Multiple dietary profiles can be selected in one adaptation so replacements are chosen against the combined request rather than applied one after another.
