Grind the whole fennel and coriander seeds with a mortar and pestle until a coarse consistency. Or, place them in a small Ziploc bag and hammer with a meat mallet, smooth side.
In a large mixing bowl combine all ingredients in the order given.
Mix well so that everything is evenly distributed.
Using an ice cream scoop - or a 1/3 cup measure - roll into balls then press slightly so they resemble chubby hamburgers - 2" in diameter - 3/4" thick.
At this stage you can freeze them as you would hamburgers.
To cook - heat the oil in a non stick frypan and brown on both sides.
Use the pan juice to fry up some sliced onion and make a rich onion gravy.
Return the patties to the gravy and cook on low until no longer pink.
Serve on top of creamy garlic mashed potatoes.
Instead of onion gravy - I sometimes simmer them in a curry sauce made of fried onion, garlic, curry powder (authentic quality) - coconut milk and crushed tomatoes in even quantities. Serve on basmati rice.
