"The Gingerbread Witch is always a show-stealer and Ella de Jongh’s performance is a good reminder why. Vocally she is highly assured, with gleaming top notes and a syrupy middle register that pulls the children into her clutches. Her vocal mannerisms brought the character to life and revealed an actor of considerable élan, all electric swoops and devilish cackling." - Benjamin Poore, Opera Wire
"Ella de Jongh brought a wonderfully rich, dramatic voice to the role, making the courtesan Silvia vividly ardent." - Robert Hugill
"...de Jongh created an emotional and psychological highlight of the monologue at the end of Act I in Rosenkavalier (as it must be). In the third act she sang and acted well with considerable poise, understated resignation and much sadness, and was vocally radiant in that trio near the end when she created some eloquent lines with much subtle expressive shading." - Jim Pritchard, Seen and Heard International
