It seems like your store is really well targeted - you have a defined niche that will appeal to the audience with an "insight" knowledge - culinary fans. The heritage info you include on the homepage is very appealing - it creates a rapport with the visitors and gives your products a deeper meaning.
When marketing to a niche like this, ads don't always work, as you can see.
A much better strategy would be work with influencers in your niche - people with large following and posting content similar to yours - culinary theme humorous content. This way you know that their audience will be most relevant and most likely to be perceptive to your content as well. Arrange a sponsored post with this Influencer - you can ask them to review one of your products and create a post on their profile. This kind of strategy is powerful and can bring plenty of relevant traffic in a short period of time. Make sure that you have defined offer ready beforehand, so you make the most of the surge of traffic.
Make sure to share your content via social media and also appear in the most relevant searches for the target keywords. I think people who would buy these items would get them as gifts for their friends interested in the culinary topic, so you'd need to think of what search terms they would use to find your products.
