Lesson 1Criteria for selecting target species for a restaurant (seasonal abundance, flavour, ease of ID, culinary utility)Define practical criteria for choosing target species for restaurant use, including safety, abundance, flavour, texture, and labour cost, then apply these filters to build a balanced, seasonal, and logistically realistic wild menu pipeline.
Non‑negotiable food safety and toxicity screeningSeasonal abundance, yield, and supply reliabilityEase of field identification and staff training loadFlavor, texture, and plating versatility in menusLabor, storage, and cost considerations per speciesLesson 2- Young dandelion (Taraxacum officinale): rosette ID, avoiding sow-thistle/lettuce look-alikes, edible parts and bitterness managementDevelop confident identification of young dandelion rosettes, separate them from sow-thistle and wild lettuces, map edible parts through the season, and use blanching, pairing, and timing to manage bitterness in restaurant dishes.

Choosing trustworthy books and digital resourcesUsing dichotomous keys and glossaries effectivelyCross-checking photos, maps, and written traitsMaintaining a species binder or digital notebookUpdating references as taxonomy and ranges changeLesson 5- Nettles (Urtica dioica and U. gracilis): stinging vs non-stinging, stem/leaf ID, safe handling and blanchingBuild confidence handling nettles by learning stinging hair structure, stem and leaf ID, and habitat cues, then apply safe harvesting, transport, and blanching methods to turn this defensive plant into a versatile ingredient.
