Street vendors prepare Street Style Nanaimo Bars with precision to guarantee quality and adherence to food safety standards.
First, they meticulously bake the layered bars, which typically start with a crumbly base made from crushed graham crackers, coconut, and cocoa. After baking, they cool the base and apply a silky custard layer topped with rich chocolate ganache.
To achieve the perfect chilling temperature, vendors utilize portable refrigeration units and insulated coolers, keeping the bars consistent at 1-4°C during service. All equipment is regularly monitored for hygiene and temperature to comply with health regulations, while rapid cooling post-preparation locks in freshness and flavor, creating a delightful treat served fresh on the street.

Low Histamine Variation of Nanaimo Bars

Street food often contains a variety of ingredients that can be high in histamines, posing challenges for those with histamine intolerance.
Unregulated preparation methods and long-standing ingredients increase the risk of histamine accumulation in foods like Nanaimo Bars, making it vital to be cautious in food choices.
Eating street food, such as traditional Nanaimo Bars, can be problematic for individuals with histamine intolerance.
Many ingredients used in this classic dessert, such as chocolate and processed sweeteners, are restricted according to the SIGHI list due to their high histamine levels.
In addition, the environment in which street food is prepared may not guarantee fresh ingredients, further exacerbating histamine food reactions.
Instructions for Low Histamine Variation of Nanaimo Bars:
- Replace chocolate with carob powder, which is permissible in moderation.
- Use agave or maple syrup instead of refined sugars for sweetening.
- Opt for coconut cream instead of whipped cream for the filling.
- Verify all components are made with fresh, safe ingredients only.
- Substitute traditional graham crackers with gluten-free, low histamine alternatives.
- Avoid any nuts that are restricted, like walnuts or cashews.
- Prepare in a clean space to prevent any cross-contamination with restricted foods.
- Layer each section in a clean dish, verifying no high histamine ingredients are used.
- Cool the bars in a refrigerator until firm, making sure they’re stored properly.
- Cut into squares with a clean knife before serving.
Additionally, it is essential to understand histamine intolerance management, which can help in making better food choices.
Video Summary
Nanaimo bars originated in Nanaimo, British Columbia, as a delightful layered dessert. In this video, we’ll explore both the authentic street-style version and an easy low histamine home version.
Street vendors whip up these iconic bars with a crumbly base of crushed graham crackers, cocoa powder, butter, and sugar. They blend the mixture in a bowl until it creates a sticky crust. Using a square baking dish lined with parchment paper, they press the crust down evenly and firmly.
Next, they mix icing sugar, butter, and custard powder for a creamy and rich middle layer. This mixture is spread generously over the crust. Finally, they melt dark chocolate and butter together for that glossy top layer. This chocolate blend is poured and spread evenly over the custard layer. Once set, vendors cut the bars into squares for a delicious treat.
For a low histamine home version, replace graham crackers with crushed rice cakes for the base. Use one cup of cocoa powder, 125 grams of butter, and half a cup of sugar for the crust. Mix these in a bowl and press the blend into the lined baking dish.
For the custard layer, substitute the custard powder with coconut milk and omit any artificial sweeteners. Instead, use one cup of icing sugar with 125 grams of butter in a bowl and mix until smooth. Spread this layer over the crust.
For the top, use white chocolate, melting it with 25 grams of butter. Pour this over the custard layer.
The final dessert visually layers beautifully and has a sweet, creamy taste with a rich chocolate finish. Click the link in the description for the full recipe!
