Mr. Roboto
Grilled sesame seed encrusted maraschino cherry.
'Sesame seeds' is not an option in Difford's list, so I had to put sesame oil.
What I really did was to lightly grill 1 Tbsp sesame seeds and, along with the fresh ginger, muddle and then infuse for about 30-45 minutes. Then finely strain to have your final product of grilled sesame- and ginger-infused cognac.

Add all ingredients to a mixing glass filled with ice. Double strain and serve with a maraschino cherry rolled in some of the grilled sesame seeds on a pick.
