Hardboil Folio An independent journal of confectionery arts

Editorial disclaimer

Last updated: November 4, 2026

Hardboil Folio is an independent culinary publication and botanical taste study. Everything on this site is offered for education and general interest.

1. Educational purpose only

Articles, flavor profiles, temperature ranges, ratios and tasting notes describe general principles of confectionery and flavor. They are not tested recipes, product instructions or professional training, and results will vary with equipment, ingredients, altitude and humidity. Anything described as a ratio or example is illustrative.

2. Hot sugar is dangerous

Sugar syrup cooked to hard candy temperatures (about 300 °F or 149 °C) can cause severe burns. It sticks to skin and keeps burning as it cools. Anyone who attempts sugar work should learn from qualified, in-person instruction, use suitable protective equipment, keep children and pets away, and have a plan for treating burns. The site cannot supervise or verify your technique.

3. Allergen advisory

Confectionery and botanical ingredients can contain or come into contact with common allergens. Please consider the following before preparing or consuming anything inspired by this site:

  • Sugar and syrups. Glucose syrups may be derived from corn or wheat. Sugar and syrups may be processed on shared equipment.
  • Tree nuts, peanuts, milk, soy, egg, sesame and gluten. These are common in confectionery and in flavor carriers, extracts and coatings. Always read ingredient labels.
  • Botanicals. Flowers, herbs, spices and citrus peels can trigger reactions, including in people with pollen allergies or sensitivities to related plants (for example the daisy, mint and celery families). Anise, fennel, coriander and cumin are examples of seed spices that some people react to.
  • Flavorings. Concentrated flavor oils and essences are not interchangeable with ordinary extracts and should only be used as their manufacturer directs.
  • Cross-contact. Shared utensils and surfaces can transfer allergens.

If you or anyone you serve has an allergy, check every ingredient with its manufacturer and speak with a qualified health professional about your needs.

4. Choking hazard

Hard candies are a choking hazard, particularly for young children. Supervise accordingly.

5. No health claims

Botanical ingredients are discussed solely for their taste, aroma and role in confectionery. This publication makes no claims that any plant, herb, flower or spice has a medical, wellness, mood-altering or therapeutic effect, and nothing here should be read as advice on health or diet. If you are pregnant, take medication or have a medical condition, consult a qualified professional before consuming unfamiliar botanical products.

6. Selling food

If you make candy for sale, you are responsible for complying with the food safety, licensing and labeling laws of your jurisdiction. This site does not provide guidance on regulatory compliance.

7. Corrections
