Slowly cook the red onion on a low heat for at least 15 minutes to let it caramelise. The longer the better! Add the red wine vinegar for the last minute.
Drain most of the water from the cannellini beans and pop in a blender.
Crush in the garlic, and add the onion granules and cooked onion mixture including all the oil and vinegar.
Blend up and season to taste. You may want to add a little more vinegar or olive oil at this point.
Use a silicone spatula to put the dip mixture into a small bowl.
Add spiders to taste!
