They are breads ideal for filling with salty or sweet ingredients. They are great with cooked ham, with pate, with salami ... but also with jam or Nutella.
The kids really like them because they are cuddly both inside and out. The pipes that you see on the surface can be substituted for a little sesame or poppy seeds. We also remind you that you can make use of some cooking thermometer for oil, and thus have its ideal temperature.
I leave you the links of some homemade patés with which to fill these loaves: Ham and cheese paté, Pate sailors, Smoked salmon pate. All very rich.
