Get 4 tōpuku kāriki (garlic cloves), chop the top parts off, sprinkle with tote (salt) and (pepa) pepper and drizzle with the noni ōriwa (olive oil).
Roast in a 160 degree oven for 45 minutes until soft and rich in flavour. Leave to cool, this step can be done days in advance and kept in a sealed container in the fridge.
As the roasted garlic cools, add five fresh kāriki (garlic cloves) to the mortar and pestle. Bash until soft and fine. You can also finely chop them and the garlic and following ingredients in to a bowl.
Add in the tote (salt), huka (sugar), paura aniana (onion powder) and orekano (oregano). Smoosh together until all combined.
Chop the pāhiri Itariana (Italian parsley) in to fine-ish pieces. Add to the garlic mixture and stir to combine.
Finally, add in the pata kūteretere (softened butter) and squeeze in all of the cooled kāriki parahunuhunu (roasted garlic). Mix to a paste. If the butter is still quite firm, melt in the microwave for 10 seconds as it is easier when soft.
Reserve 1/4 cup of this garlic butter mixture to baste onto the hot buns.
