Quickest way for hotdogs

Hi,
I'm in the process of opening a food unit with my husband.
We're serving probably 3 varieties, bought precooked and heating them up ourselves. We don't want to keep customers waiting (they'll be queueing outside), and and wondered does anyone have any advice as to quickest way to cook? We have an electric griddle, so planned to griddle then hothold in the bain marie. I had thought of putting a drain plate in the bottom of the bain marie with a little water underneath and steaming them, but I've just read that I can't cook food in the hothold equipment? Obviously that would take longer too, but it would mean they could cook themselves while we were busy? Any advice appreciated! 😁
Thanks
Cleo

Hi Cleo,

Sounds like you’re setting up a great little operation! Speed of service is key when customers are queueing, so let’s go over the best ways to keep things moving efficiently while staying within food safety regulations.

Can You Cook in a Bain-Marie?
You’re absolutely right—a bain-marie is for hot holding, not cooking. It keeps food warm but won’t bring it up to a safe temperature fast enough. If you put food in there cold or even lukewarm, it could sit in the "danger zone" (8°C - 63°C) for too long, which isn’t safe.

However, a drain plate with a bit of water underneath is a great idea to prevent food from drying out once it’s already hot.

Faster & More Efficient Reheating Methods
Since you’re using an electric griddle, you’ve got a solid plan, but here are some tweaks to make service even faster:

Preheat the Food in Small Batches

Instead of cooking everything to order, griddle a batch just before the rush starts.

Once hot (above 75°C), transfer it straight into the bain-marie, keeping it at 63°C or higher.

This way, you're always a step ahead and only have to top up rather than cook from scratch.

Use a Combination of Reheating Methods

A griddle is great for texture, but it takes time to heat food through.

Consider a commercial microwave to get items hot fast (especially for dense or thick foods) before finishing on the griddle for texture.

This is a common trick in busy street food setups!

Hot Water Bath (Sous Vide Style) for Faster Bain-Marie Use

If your food is vacuum-sealed or in heatproof bags, you can preheat it in a deep water bath (or a large saucepan with simmering water).

Once it’s hot, transfer it straight into the bain-marie, where it’ll stay at the right temperature until serving.

Portion Control for Speed

Rather than heating big trays at once, work with smaller portions—they’ll heat through quicker.

If using the griddle, flatten or slice thicker portions to heat them evenly.

Final Tips for Smooth Service

Test your setup before opening—run a full-speed practice service to see where bottlenecks happen.

Label and rotate food correctly so you always serve the oldest (but still hot) portions first.

Have a backup reheating method in case the griddle gets overloaded.

With the right prep and reheating flow, you’ll keep that queue moving while serving great food!

Hope this helps—best of luck with your new venture!
