強め
"強め" means "strengthening" or "intensification."
Here, '強め' is used as an adverb (in its adverbial form '強めに'), modifying the verb '作って' (make), describing the manner of the action.
風味を強めにして作ってください。
Please make it with a slightly stronger flavor.
In this sentence, '強め' acts as a noun, followed by the copula 'だった', indicating the state or characteristic of the attack being stronger.
あの選手の攻撃はいつもより強めだった。
That player's attack was stronger than usual.
Here, '強め' is used similarly to the first example, as part of the adverbial form '強めに', suggesting the intensity of assertion for a more impactful delivery.
