てもだいじょうぶtemodaijoubucolloquial
味あじわってもだいじょうぶ
usually written ても大丈夫だいじょうぶ — a softer, casual reassurance swap for 構かまわない.
てもかまへんtemokamahenregional
味あじわってもかまへん
kansai-dialect negative of 構かまう — this one uses the standard て-form (買かってもかまへん); true Kansai often drops て entirely (買かうてもかまへん／買かうても), so it's an approximation.

構かまう means "to mind, to care about" — ても構かまわない literally reads
"even if you do, I don't mind," which is why it lands cooler than てもいい.
