The delicious details

Blossom by KP is a conscious cafe-restaurant on the Botermarkt in Leiden, where vegetables take the leading role and flavours from Mediterranean and Middle Eastern kitchens meet global influences. The largest part of the menu is plant-based, colourful and freshly prepared, with breakfast, lunch, high tea and a shared mezze dinner served several evenings a week.

The setting is relaxed and bohemian, with a lounge feel indoors and a sunny terrace beside the water in the city centre. A children's play corner makes it an easy spot for families.

The kitchen works with seasonal, local ingredients and runs a deliberately low-waste operation, fermenting and preserving what is left at the end of the day and cooking on green energy.

Menu
What's on the table, and what's left off

Vegetables lead the menu at Blossom, with a plant-based majority of falafel, hummus, roasted beets, tempeh and house-made mezze. The kitchen ferments and preserves seasonal surplus, bakes cakes in-house, and accommodates vegan, vegetarian and gluten-free diners.

How this restaurant rates
3 - Endorsed

The kitchen follows the seasons, building its dishes around seasonal, locally sourced ingredients rather than a fixed year-round card. It also runs a deliberately low-waste operation: surplus produce is pickled and fermented instead of discarded, the kitchen buys with care to limit waste, and the restaurant runs on green energy.

Vegetables are the heart of the menu, with the largest part of the offering plant-based and animal products kept to a small, considered selection.

Website states seasonal, local ingredients but names no specific farms or growers.

The kitchen describes working with 'seizoensgebonden, lokale ingredienten' (seasonal, local ingredients), but no named suppliers, farms, growers or regions are published. The claim is self-declared and unspecific, supporting only a low engagement score.

Strongest sourceRestaurant submission

Menu reflects seasonal availability; preserved and fermented surplus from end-of-day practice.

The restaurant builds its menu around what the seasons bring, describing seasonal and local ingredients as the anchor. It also ferments and pickles end-of-day surplus produce, a concrete seasonal-reuse practice independently confirmed by The Green List vegan guide. The menu changes with the seasons; this signals regular engagement with seasonal availability rather than a fixed year-round card.

Strongest sourceRestaurant submission

Ferments and pickles surplus produce; buys with care to minimise waste; operates on green energy.

Blossom's low-waste practice is named and concrete: the kitchen ferments and pickles end-of-day leftover produce, reducing waste through creative reuse rather than disposal. It buys with deliberate care to minimise waste at source and operates on green energy. The fermentation and pickling practice is independently corroborated by The Green List, which describes the restaurant as committing to low-waste through preserving leftovers, giving credible evidence of a multi-part, named practice.

Halal chicken and beef options; no named welfare certifications or fish specifications.

The menu includes a small, considered selection of animal products: halal chicken and beef described as 'carefully chosen', and tuna. No welfare certifications (Beter Leven, organic) are named, and the tuna species and catch method are unspecified. 'Carefully chosen' is a vague self-declared claim without substantiation or independent corroboration. The animal products sit alongside the plant-based majority but remain untraceably sourced.

Strongest sourceRestaurant submission

Vegetables lead the menu; largest share is plant-based; small, deliberate animal selection.

Plant-forward cooking is central to Blossom's identity: vegetables are described as 'in de hoofdrol' (in the lead role) and the largest part of the menu is plant-based, spanning falafel, hummus, roasted beets, tempeh and house-made mezze. Animal options are limited and deliberate—halal chicken, beef and tuna. The commitment is independently corroborated by The Green List's vegan-dining guide and by HappyCow's listing, both of which recognise the restaurant for its plant-led menu. The menu is vegetable-dominant by design.

How we score
The My Treats impact scale

Every restaurant is assessed against SEERO, our six-dimension sustainability framework — covering sourcing, seasonality, waste, animal products, social impact, and plant-forward cooking. Each finding is weighted by how strongly it is corroborated. The combined result is translated into a planet rating from 1 to 5.

The five levels

SEERO is an acronym for Starting, Engaged, Endorsed, Recognised, Outstanding:

Starting First verified signals of sustainable practice.
Engaged Credible practice across two dimensions.
Endorsed Meaningful practice across three or more dimensions.
This place
Recognised Strong practice across four or more dimensions, with independent corroboration.
Outstanding Top-tier practice, confirmed by recognised third-party audit.

How a level is reached. Each level needs two things together: a minimum number of dimensions covered, and a minimum overall strength of evidence across them. A dimension only counts once its evidence is specific and substantiated — a passing mention doesn't qualify. Meeting only one of the two keeps a restaurant a level lower.

Ratings of four or five planets require human validation and, at the top tier, an external audit. Scores are based on publicly available evidence and restaurant submissions at the time of assessment.

How evidence is weighted
Self-declared Stated by the restaurant on its website, menu or in a submission. Plausible, but not yet independently corroborated.
Researched Found through independent research; one credible third-party source backs the claim.
Vouched Corroborated across more than one independent source. Some gaps may remain.
Audited Fully corroborated across independent sources or by a recognised third-party certification.
What the sourcing checkmarks mean
✓ Full check — independently verified: corroborated across more than one source, or audited / third-party certified (vouched or audited).
✓ Light check — self-declared or from a single source. Not yet independently verified.
